It's not a bad printer. Watch some reviews, but my impression is pretty positive, fixes some of the issues of the original Core One. Looks like there are some less ideal features (like the shitty camera), but it's a pretty moddable printer. If you ever want to upgrade it, you can be fairly sure that Prusa will have various upgrade paths into the future. INDX being a main one. The open source firmware and permissive attitude towards hardware mods is definitely nice.

If you don't want a printer that you can modify or upgrade, and don't care about open source, you are spending a fair bit more money compared to its competitors. That goes not just for the printer itself, but any branded accessories and consumables. If you want a good modern printer without any modification at all, you'd probably be better off buying a printer that comes with those additional features, like chamber heaters and such.

Buy X2D now or wait for Anniversary sale? (I faintly want a H2C, but what I really want is a toolchanger)

Can I assume ironing settings will work fine for the same filament, same brand, different colour or do I have to dial it in for colours as well?

>>2993029
I doubt that anything serious will come of it, 3D printing is too widespread and I don't see how they could enforce the laws they want to pass. That said it sure would be great if politicians could stop being neurotic control freaks for 5 fucking minutes
>>2993076
if you can wait then buy when there's the sale of course, that said even with a discount the H2C will probably still be 2.5-3X the price of the X2D

>>2993078
Yeah. I think the X2D is what I should get, but I do want something like the U1, but with a more contained filament system, not as noisy and not having to pay like a $200 premium to get a plastic lid on the damn thing.

>>2993079
>not having to pay like a $200 premium to get a plastic lid on the damn thing
lmao I just looked it up and that's really the case (well only $150 if you preorder now!)
imho your main questions to choose between the two should be whether you mind the bowden extrusion on the second nozzle, and how often you'll use 3 or 4 colors/materials in a print over just 2

>>2993079
Just do the ikea plastic tub lid, you can stack two tubs to get something with impressive thermal insulation.

Best "tough" cheap pla? Polymaker pla pro is great but I wouldn't be mad at spending less. Needs to stay at the same quality/print ease otherwise I would rather just spend more. Overture super pla + maybe? Will also be picking up in bulk since I've been burning through filament lately, so any bulk offers from the manufacturer are a huge plus.

This stupid thing. Entirely 3D printed except for the knobs, that I had a small stock of.

Looking into a vertical storage system for my hobby table. I'm stuck between regular pegboard, Ikea skadis, and opengrid.

Any advice/pros and cons? What did you go with?

>>2993134
oh wow, I missed that completely. Thanks for the heads up. Now that its in the thread its more likely to make it in the next one.

>>2993144
pegboard is widely accessible and you can print fixtures but it's better for hanging stuff like tools or a bag organizer (I used to have a wall of backpacks and fannypacks in pegboard) and the big annoyance is if you don't lock the clips they knock out easily.

Gridfinity looks good and there seems to be a skadis based system out there (someone selling on my local cl but I haven't seen it in the wild. There is also multigrid. I don't like the looks of open grid, multi or gridfinity seems best although I think one is locked behind patreon walls. And then do you want to spend the time and money producing all of them? And can your printer handle the quality to make shit actually fit? I always struggle with other people's designs so idk.

TPU works for toothed belts, but it’s not high enough friction for a flat/square belt. To get friction it needs to be under tension, but TPU creeps badly.

>TPU works for toothed belts, but it’s not high enough friction for a flat/square belt. To get friction it needs to be under tension, but TPU creeps badly.
I've literally done it and have been running belts that are fine since 2021

all friction belts need tension, you don't even know how your own car works, are you a bot?

>>2993172

Yeah, and TPU creeps. But I guess it creeps under bending loads, not as much under tensile loads.

This is the very first thing I actually tried to make from scratch. I keep getting a constraint flip in FreeCAD. Hopefully someone can help me out here. Let me over-explain my process here.

I'm making a little organizer for a board game that I can resize. Just 4 bins divided by a 1.5mm barrier between them. What you're looking at here is the pocket I'm carving. For the inner walls I have the edge of the pocket coming in 0.75mm, then I polar pattern the sketch around the center point of the main body 4 times to make 4 pockets. When I resize the width, the constraint for the inside wall of the pocket flips to the other side of my origin line here, pic related. It looks like I've got the outside walls working, but the line for the inside walls keeps flipping to the other side. I've been googling around and the solution is 'tie the dimension to the variable'. Okay, great. Worked for the outside walls. I want the inside walls to be 1.5mm, any formula I put in there is going to scale the size of the inner wall. This dimension should always be 0.75mm in from the center line. How the fug do I get that set so it doesn't try to flip the constraint? Is the process I'm going through here just flawed from the start? I feel like there is a simple solution staring me in the face but I'll be damned if I can see it since this is my first dive into the program.

>>2992972
how do you guys connect filaments? is there a sure fire way to join filaments on the cheap? I saw the method using a silicone tube and a soldering iron and did that, not to long ago that first joint appeared and i was able to watch it and it broke in the print head. The print head started clicking but i was able to push the filament and the feed motor got it and it kept going. I may have over heated it? the joint wasn't a big mess but it wasn't like brand new smooth

>>2993199
Not FreeCad, but I often draw diagonal construction lines from the outer corners to the inner corners, and specify them being right angle/parallel to one another.

>>2993206
Why would you want to do that? To save the few metres of filament left on the spool? Or for multi-colour bullshit? If the former, just use the remnant filament for little useful things like organisation boxes. If the latter, use pauses instead, and if that's too inconvenient use something like an MMU.

>>2993199 That's strange, anon
Are you sure it's a constraint and not a measurement ?
Also is it a horizontal distance constraint ?

>>2993078
>I doubt that anything serious will come of it, 3D printing is too widespread and I don't see how they could enforce the laws they want to pass.
Maybe, but the california one already passed committee, and the New York one is still in the budget AFAIK. I wouldn't underestimate it.

>>2993199
seems that the issue is that FreeCAD doesn't use signed constraints so it doesn't really know what side of the line that point should be on, you could make a little 0.75mm construction square with the bottom right vertex in the center and then constrain your pocket square to the top left vertex.
Also personally I'd just sketch all 4 squares with the appropriate constraints but from what I understand it's bad CAD practice?
And a multi-transform with two linear patterns should give you direct control on the distance between the pockets, but if only need a 2x2 a polar pattern is probably a cleaner approach
>>2993228
that's crazy, are 3D printed gun parts even an actual problem in the US? Can't you just easily scrape off the serial number from a normal gun or create a make-shift gun with normal tools anyway?

>Also personally I'd just sketch all 4 squares with the appropriate constraints but from what I understand it's bad CAD practice?
>bad practice
It is.
Except with FreeCAD it is the most reliable way to get things done, SPECIALLY (and I cannot stress this enough) if you're using some of their "weaker tools", aka anything that uses booleans (or implicit booleans).

>>2993232
I would create a symmetry against the vertical axis to create the second square then another symmetry to create the 3rd and 4th, put dimension constraints on the 1st square then put symmetry constraint on the rest.
>seems that the issue is that FreeCAD doesn't use signed constraints
it should, there's a direction for the dimension constraint and it can be -1, 0 (not applicable) or 1

Not really, but Luigi shot the guy with a partially 3D printed gun, and it seems like Western govts are in a mad scramble to regulate personal tech. Also, these states are run by people who absolutely hate the 2nd amendment and personal gun ownership.

>>2993234
but why is it bad, is it just because of scalability or is there some other reason? If you constrain the squares properly everything should still be able to change the variables later, and pocketing one "complex" sketch seems less intensive computationally than making an array with a pocket
>>2993235
>it should
I have no idea why it doesn't, I've also had issues with things jumping around after changing a dimension

I think that between Abe and the United Healthcare cunt, the elites are pretty concerned about the direction this is going.
3d printing is absolutely the easiest way to make a gun. You don't need to tell me about an 80% parts kit and a jig to machine a lower receiver but 3d printing makes it way more accessible for people who don't know shit about metal working.

>>2993275

If you get mosquitoes then you'll want a proper gauze mesh over the back too.
You could tape over the hole with the tubes and plug that with construction foam too, then when it's dry, remove the tape and cut the foam flat and maybe paint it.
It would look even better and not leave a gap.
Alternatively, some sort of TPU plug, let the inherent creep mould the TPU to fit the tubes over time.

Some of the places in Japan that are hotspots of longevity have been very well studied.
Look up Ogimi some time.
Some of it is diet but a lot of it is cultural too.
For one thing, they tend to work until they die, not necessarily for a wage but at least gardening and community stuff.

Their diet is very diverse with meals typically containing over thirty different plant and animal ingredients.
There's a cultural tendency to reject eating until full and to stop while still slightly hungry.
A bunch of other stuff go into it too.

At least it gets somewhat toasty. It's sitting at 65C after an hour of passive heating without extruder heating or movement. Broke the drive belts (cheap chinkshit) so waiting for some proper Gates belts before I can print anything.

>>2993630
That's beautiful mate. Too bad about the drive belts though, was that from the heat or what?

Any reason you went for duender instead of an e3ng?

>>2993697
>Too bad about the drive belts though, was that from the heat or what?
NTA: nobody ever told me just how tight a drive belt is supposed to be.
Anycubic were surprisingly cool about it and sent me new ones but even they couldn't actually define "tight enough".

>>2993713
Engineer here. Tight enough means jack shit obviously, but that's your bog standard recommendation because fuck you I guess. Proper belt tensioning is constrained by two parameters: the strength of the belt and the maximum radial force the stepper shaft can handle, so you pick the lower of the two and remove another 10% for good measure. The proper tensioning value is easy enough to figure out, since it's just a couple of TDS away, but the real kicker is measuring it: it's not that easy. The quick and dirty way is taking a known length, plucking it, and using a spectrum analyzer app to measure its resonance frequency and from that you derive the tension, but from experience that method sucks balls. Alternatively you can print a gizmo that will indicate the right tension for your belts, but it needs a specific piece of spring steel wire that is kind of unsourceable, a specific piano wire IIRC. In the end the juice is not worth the squeeze. Just tighten it enough to prevent low frequency resonance, while keeping an eye on your motors to check if they're overstressed.

They will get hotter

On my classic ender 3 i've tightened the belts by hand without using levers or other implements, they should be tight but not enough to make noise like a guitar string when plucked

>>2993748
>>2993757
Tight enough = Taut and a bit more to make it tight enough

>>2993766
>they should be tight but not enough to make noise like a guitar string when plucked
I think that's how I snapped them, they were tight enough that they didn't move much when I plucked them.

>>2993769
>Tight enough = Taut and a bit more to make it tight enough
The replacements got that sort of treatment. I at least knew at that point how much was definitely too much.

>>2993757
Sorry I had to specify: low frequency resonance according to the input shaper. The calibration will measure the frequency response of the tool head (and the bed for a bedslinger), a belt not tight enough will show as a shitty response with lots of resonance.

Thank you anon, i was blindsided by the problem, if the "flat" of the nut is parallel to the surface of the feature there will be more material. Thank you a lot.

i messed up the part anyway, hole was supposed to be for M5 but I made it 4mm in diameter for whatever reason, so back to the drawing table. I'll put a bit more tolerance for the dovetail slot too, it could slide in but with a lot of work on both parts.

>>2993748
real engineers do it by feel. I remember in college we had to interview graduates who were doing engineering, we got a pre-drone RC helicopter manufacturer. RC heli's were notoriously expensive and extremely fragile, their business model was to make big cheap RC helis you could smash into a bridge pilon and only be out a hundred dollars in "consumable" parts. in any case our group asked how they make sure like the rotor doesn't fly apart, how do they calculate the stresses. the guy laughed and said we just pin one end of a rotor to the roof beam and have the fattest guy in the shop hang on it. we figure if it holds, it will be fine in production.

Another solution would be to print a weighted base that the stand fits into, something you could insert some lead washers/sinkers/curtain weights into. Possibly even as a pause while printing.

>>2993997
the clearance between the spinny bit and the top plane of the base circle is very thin. one big 55mm washer would probably work with a thin skin, otherwise you'd have to stack things around the rim to avoid interference but a nice big bearing race could work well too. as a bonus I wouldn't have had to measure the damn window sill molding.

>>2993999
Terminology:
>the base circle is the "foot"
>The vertical beam is the "spine"

Start with a cylinder that is slightly wider than the foot's diameter, maybe 1cm for 5mm clearance on each side. It should be quite a bit taller, maybe an inch or so.
Subtract a circle the height and diameter of the foot from the top of the cylinder, this is where the foot rests.
Add little chamfered clips to three cardinal points around the circle, these will snap over the foot when it's inserted and hold it securely.
Add a vertical outcrop to brace the stand's spine so that it gets a bit of extra support and design a clip that snugly holds the spine in place

You could make the cylinder two pieces that unscrew to hold weights in a compartment underneath the foot, or you could insert the weights during a printing pause if you prefer.

Why is Prusaslicer retarded? It thinks the first flat layer on top of support material is solid infill and not a fucking bridge. Likewise there's zero interface layers between the top of an object and new support material printed on top if it.

Interesting looking stuff. A bit limited at the free tier though (can't import 3D scanned meshes, can't import or export STEPs), and the proprietary nature gives them the ability to change their terms of service at any time and lock you out of your files. But no worse than Fusion 360, and I'd probably trust RS more than Autodesk or Adobe or Microsoft.

>>2994061
>You just can't use their servers with another slicer
They didn't even prevent you from being able to do this. The linux BambuSlicer has no software authentication method, so you just copy that GPL licensed code that connects to their server and it will still work. If they wanted to prevent people from using their cloud server, they'd publish the source code for their server-side network plugin (as they are legally required to via the GPL) and bambu printer owners could use that with a different slicer and a different server. Alternatively, if they stop the network plugin from being an integral part of their slicer by compartmentalising it (hence likely allowing other network plugins in bambuslicer forks), it would no longer fall under the GPL licensing terms so they could keep that code closed source and make it more secure.
They just can't have their cake and eat it. They're the ones who chose to fork GPL-licensed code.

Jesus christ dude. Yes, it's the slicer's fault when it uses types that don't match what it should be using. Yes, the model is a pain in the ass. Yes, I am dealing with faulty hardware, they're sending me new cables because of it. Manual supports wouldn't help because I'm already having it support pretty much everything, and even then I do actually have them. Organic would make things worse because I need the stability of being able to attach to existing supports to build the new supports on top of the PETG surfaces. I've been doing this for a long time and I'm pretty good at it, but even then I occasionally run into some bullshit I never expected. Hell, the boxes and rods I added here >>2994052 are explicitly because I knew there was no way in hell those nubs were going to stay in place, and before the printer failed they worked perfectly.

I will proceed to not follow "the rules" and use their cloud servers with 3rd party software. Bambu's fault for making it trivial to access.

>>2994007
It should be bottom layer speed I guess? Might be able to edit the g-code manually and change the speed of that section. Maybe if you add a trivially small support gap (e.g. 0.01mm) you could change what type it uses, but I doubt it. Either way I'd put an error report on the github.

I'd also look into splitting the model to make it easier to print, with alignment holes so you can slot it together with pins. While on the topic of editing the model, making the underside of those pins slightly conical would make it print all perimeters for the parts of the model in contact with the support interface.

If your print artefacts are minimal and the prints come out pretty isotropically, you could also prop the whole print up on 45 degrees with liberal use of tree supports. It's a meme technique, but it might do the trick. Maybe you'd still add manual support forms and fins to critical areas.

>>2994052
>It needs to be zero because I'm printing with PETG using PLA supports
Then it's not bridging or doing anything special extrusion wise. It's physically printing directly on top. What do you want if not the parameters you've set for perimeters and infill?

>>2994083
His problem I believe is that it's using the high-speed solid-infill profile for that part, but because it's printing on top of PLA without as much adhesion as if it were printing atop more PETG, that's too fast and it doesn't lay down properly. For the same reason that the first layer of a print is done slowly, the layer atop a different material support interface should probably be artificially slowed also. I've heard others complain about the poor adhesion of support filaments causing print failures, but that might have been in the context of soluble supports.

>>2994062
>I'd probably trust RS more than Autodesk or Adobe or Microsoft.

Are custom made diy 3d printers still around, or did bambufag's packaging of open source designed stuff into a commercial product finally kill them off for good?

He’s answering the question in the OP with another source.

>>2994099
The proliferation of 3D printers made lots of components easier to get that weren’t an option in the mendel days. Online shipping improvements helped too.
And it’s now more cost effective to buy a printer than make a printer at almost any price-point, at least all the ones under 600USD, so the only sensible reason someone would build a printer is that they’re after superior specs or a specific niche. Maybe an ultra hot heated chamber, or an IDEX, or a pellet extruder, or an extremely tiltable bed for non-planar printing, or the ability to print 20A TPU, there’s still lots of valid reasons to make a custom printer. Or at least to modify a sufficiently open printer.

Getting ready to print ASA for the first time. Bambu X1C. So far:

1. bought a fan, printed a vent duct coupler, going to sticky-tape the fan to the back of the printer over the exhaust vent to suck air out and blow it out my bedroom window.

2. bought one of those ceramic heating things and a temperature controller to stick inside the X1C enclosure right next to where the bed moves up and down. Plan to set them to 80C.

Should I tape up the X1C enclosure so that air can only enter through the bottom edge of the front door, or is that not really necessary?

I've read mixed comments on whether to use gluestick on the PEI bed or just use the plain PEI bed. Planning on trying just the PEI bed first. Is this viable?

Am I missing anything else that I need to do?

>>2994178
I dont think printing ASA is that big of a deal, just open a window. Also, fuck glue sticks get on the unscented hairspray train. Spray that PEI plate really quick wherever your print came up and put it back in there.

>>2994178
>exhaust fan
If you're trying to preserve chamber temperature, you may want the ability to turn the fan speed down. Also to prevent leakage, you're better off having the fan at the window, sucking down the tube, as opposed to at the printer, blowing down the tube and potentially out any gaps.
>80C
Do you intend to regulate the chamber temperature to a homogeneous 80C, or just the output airstream? If the former, check the maximum operating temperature of printer components. Fans especially are known for not liking more than 60-70C, and components in your toolhead board might protest also. Stepper motors and drivers will run hotter than that still as they produce significant internal heat, so extra heat-sinking might be required, if not additional active cooling. Most people settle for 50-60C for ABS/ASA printing, I'd try that first to see what kind of warping you get, if any. If the latter, you're better off regulating the internal temperature properly. Your exhaust duct also needs to be able to handle the heat of the air, now there's a chicken and egg situation for you.
>tape
If you want to minimise fume leakage, the best way is to ensure there's negative pressure everywhere fumes are present. To ease the burden on your fans and on your chamber heating, taping up gaps may well help with this.
>PEI
Textured PEI shouldn't be damaged by the printing, while smooth PEI is more delicate and I'd only use it for PLA. I see many people using the Bambu engineering plate with glue, but if it's not a warp-prone model (i.e. it's flat and has round corners) I'd try without glue.

>>2994180
what's a good glue? I'm trying printing ASA on an open printer and I have some issues with larger models

>>2994169
let me take a guess. You never had a problem with this in the past and you upgraded to FreeCAD 1.1 just recently?
It's pretty much what this >>2994176 anon said.
I had the same problem. For a better explanation and a fix watch this video:
https://www.youtube.com/watch?v=fstXygscASo
(it's less than 5 minutes of your time)

>>2994182
No clue sorry, I have an ender 3 with a K1 bed so for all the filaments I can print my adhesion is perfect. I think it depends a lot on the filament you're printing, because glues can serve one of two purposes:
>hold the print to the bed at the bed temperature during printing, because the filament doesn't stick well to the build surface
>stop the print from damaging the build surface when removed, because the filament sticks too well to the build surface
And that first one is temperature dependant. A glue that works well on ABS might be useless for TPU. The glue also has to adhere well to the build surface itself, so glues might behave differently with textured vs smooth PEI, and differently again with glass or PET or PEY or whatever.

>>2994189
thanks, sadly after a bit of searching I still can't find a straight answer other than "you shouldn't need glue for ABS/ASA"
I'll try heat soaking my makeshift enclosure for longer and turning off the part fan completely, if it still doesn't work I'll give the classic glue stick a shot

I can't tell if this is a clog or this abs needs drying. It's...odd. I've never had to dry unreinforced abs even with *years* just hanging out.
A few days ago I used up the last of some abs-cf core I had, and while it was dry(about six hours in the dryer+during print) it still printed with an opaque/dull fuzzy texture, while prior instances it's been glossy even with the reinforcement.
Changed filaments for a quick part, tried straight abs, and this is the result I get. Moisture in the little experience I have with it doesn't show up like this, with the first layers being unaffected and the later ones only intermitently. At worst it's the outer windings causing issues with the first few layers and it's fixed by the time they're used.
Generic abs, two walls, 0.6mm nozzle, 65c chamber, 270 nozzle, 90 bed.

>>2994202
The reason is even if you were to use the best glue possible abs's shrinkage will split the part elsewhere. the only solutions to printing large abs and memeSA is a heated chamber or clever geometry.

>>2994216
I see, I guess I should just accept the limitations of my setup and work around them rather than brute-forcing prints too cumbersome for it

>>2994182
issues with them sticking to the plate? pei plates vary as with mine I can't print ASA or PETG but others report they can print PETG just fine. not sure about ASA, I do print it but on the bambu hot plate. glue stick always helps, hairspray as well. purple school glue leaves a residue whereas bambu glue stick does less and hairspray the most even and least. mouse ear skirt, skirt, and part design can all play a big part too. it's not as simple as "ASA no worky" you have to give more info and pics.

>>2994182
use unscented aquanet hair spray(or equivalent). You get to just spray it on the plate.

>>2994213
If you look at it in the slicer, do the bands correspond to shorter layer times or some other variable? Can’t think of any other reason it would be worse at the top of the model, and feasibly a cubic-like infill pattern could cause the layer time to vary significantly in a periodic fashion. Though the matte bands seem to be closer together lower on the cone, so maybe it’s periodic on the spool itself.

I guess give it a dry, and swap nozzles if you have a spare.

I'm half tempted to slice these nubs off and dissolve them onto a specimen glass with some acetone to look for either carbon fibers or glass fibers... somehow.
the black looking scale is from the sealing surface of the nozzle/heatbrake interface moreso than there being burnt shit inside the filament path.

oh hey, it's done.
since the previous nozzle was a tungsten one, I'm running 280c on abs, switched to a standard plated copper one which transmit heat much more readily. Printed mostly fine but the filament with the more conductive nozzle was clearly cooking near the top where it starts to slow down.
The filament has not been dried in between >>2994213
and picrel. It's also not brandless abs, it's sunlu abs.
What I'm struggling to comprehend is why a partial clog somewhere in the heatbreak/nozzle is causing an overextrusion/overdimension similar to wet filament, and mixing to a degree that it turns glossy core filaments into non-core matte ones.

>If you're trying to preserve chamber temperature, you may want the ability to turn the fan speed down.
Good point; while I can set that up in the future (easy with a RasPiZeroWH and two wires connected to GPIO, maybe throw in a potentiometer or at least a couple of buttons for faster/slower if I want to be fancy), right now I just have a straight 12V power supply.
>Also to prevent leakage, you're better off having the fan at the window, sucking down the tube, as opposed to at the printer, blowing down the tube and potentially out any gaps.
My tube only needs to be about six inches long. I'll probably slice off about a foot of duct tube just to be able to move the printer around a little.

>Do you intend to regulate the chamber temperature to a homogeneous 80C
Yes. AFAIK Bambu X1C can handle it, but I'll check. I can always start lower to test.

>Textured PEI shouldn't be damaged
I think my plate is textured. Wish I could've gotten an "engineering plate" before Bambu discontinued it. :-/

>>2994284
the engineering plate is just pei with some additive iirc. I'ts kinda reduntant and pointless especially for asa/abs. even pps-cf will print perfectly fine on regular pei.
Most of the time textured plates have lower bed adhesion but they also release better and are thus less likely to be damaged. glue stick/spray/bed conditioning is often used more for a release agent (petg, tpu) on pei beds than it is an actual adhesive.

I just restored my old Ender 3 I had lying there because I needed another printer for some project and it now performs better than when I replaced it with an Artillery Sidewinder X2.
Now I'm considering upgrading to a Bambulab X2D, mostly because of printing supports with different materials sounds nice.

Is it worth it over a Creality K2 Plus for the support thing or it's just a skill issue?
Also, how much is the speed improvement when upgrading to a CoreXY printer?

I have an A1 mini in a makeshift enclosure (holds a bit of heat and protects from drafts but nothing more) the 80°C max plate temperature is the real issue without a heated chamber. I have to print a flat ellipse-shaped part that's like 15cm long, even with a generous skirt one side always lifts a bit from my cryogrip plate (I don't have pics nor the piece at hand but the last time the deformation was small enough that the print still managed to complete and is almost usable, I figured that the warped edge was sitting in a spot where the plate is a little colder but on such a small printing space I don't have the freedom to move it around much) but next I'll try bambu's original pei plate with glue, or this >>2994228 if I find any around the house.
Oh and I turned the plate to max temperature some 20 minutes before starting the print, but the warping only happened around an hour or so into the job. I used the criogrip plate because it holds onto PLA much better than the standard pei plate, but I failed to consider that it might lose "performance" at higher temperatures or that it just might not adhere well to ASA

Redpill me on Klipper, I have an Anycubic i3 with some hack I did years ago that enabled mesh bedleveling and it works great.

Are they solid carbide, or do they have a carbide insert? I looked a while ago and they were pretty expensive, I think copper nozzles with a hardened steel insert is a good enough middle-ground for 99% of prints.

>>Do you intend to regulate the chamber temperature to a homogeneous 80C
>Yes. AFAIK Bambu X1C can handle it, but I'll check. I can always start lower to test.
So it turns out that whatever page was recommending 80C was on fucking acid or something, 55C is recommended for ASA, and Bambu apparently maxes out at 60C before electronics start flaking.

Anyway, I'm trying to download a temperature tower off MW now and it's being Chinese asshoe, but I'll probably start printing tomorrow.

>>2994431
80°C did sound pretty high, I know that generally ABS starts deforming at around 100°C but according to some sources its HDT can start at 80°C, so having to go that hot just to print it was a bit much.
You can get a temperature tower STL from any website, it'll be an excuse to learn how to change the nozzle temperature manually at select layers yourself

i want to try printing pla in an 80+ chamber, with some sort of qidi-like cooling system to prevent heat-creep
maybe it would anneal itself as it prints?

>>2994458
or maybe it'll creep and curl.
which is what happens in my unheated voron2.4, and which is why im working on a cpap build to pull cool air for outside

>>2994459
can't you just use a much lower bed temperature? I think that once upon a time people used to print PLA on a cold bed

>>2994460
anon, of course im using an unheated bed, on a glass sheet, with painters tape.
but you gotta understand, the hotend on my printer goes HOT because im printing fast, any time i print something bigger than a benchy the printer will be pumping an ambient 70+ anywhere near it.
doesn't help i live in aus and we can get the 40c days.

the issue is that the hotend cooling fan is pulling the air from RIGHT above where the hotend is sitting at 260c, so the cooling fan is pushing hot air.

hence my plan to cpap even a few dozen cm away to get cold air through, or even toss a duct out the window and pull some cool nighttime air to print overnight.

I'm ripping the guts out of a makerbot z18 and replacing it with a modern printer mother board. (I've been talking about this for a while but it's actually happening now. I'll be sure to post updates if anyone is interested)

I have an octopus pro board and I'm now deciding what stepper drivers I should get and where I get them from. I'm looking around on my own as well but in the meantime, does someone want to redpill me on these things? Should I just buy them from BTT too?

>>2992972
I wan't to switch from SLA to this kind of printer. But what's the biggest difference between Bambu Lab P2S and X2D? Is the 100€ jump worth?

>>2994519
for the most part stepper drivers are kind of all the same for printers.
theres the cheap ones, which cause motor whine.
and the less cheap ones which dont whine, and you can dial in the voltage on them.
then you enter CNC motor drivers are its not a chip anymore, its an entire module.

just get the BTT ones

>>2994521
Heated chamber and a dual nozzle for printing supports and multiple materials, which makes it excellent for engineering purposes. If you plan on doing 2-colour printing, it will vastly reduce purge waste, but if you’re getting an AMS or two and using more than 2 colours it’s not that much of a purge difference. If you’re only printing with single colour PLA or PETG, the ability to print breakaway or soluble support materials probably still makes it worth getting.

All this is assuming you don’t have any moral objections to the bambu botnet and GPL violations, and don’t believe any of the new 3D printing regulations will effect you.

>>2994533

fill me in. only worked with elegoo so far

>>2994535
Bambu wants to know what you're printing, makes their printers phone home and rat on you. If politicians get their ignorant laws passed bambu will have legal backing to say "you can't print that", and effectively turn off your toy remotely.

>>2994535
its a lot like the 'discussion' on how toxic resin is.

one side says wear PPE any time you enter the room adjacent to the printer

the other side say they drink their waste IPA

except for the bambu 'situation'
its one side says the printers are sending every model you print to china so they can add spikes to your butplugs and sell your company secrets to the american government so they can tell disney and lockheed you're impinging their IP of guns and cartoons.
and the others say the printers report basic telemetry for the sake of knowing what they should sell more of.

>>2994537
bambu was taking all my data long before the government got involved. the salient point is they will be able to sell their printers under the laws and others won't simply because they have the report every print to home already implemented. but come on they're chinese, when have the chinese ever cared if you printed disney's IP

Gonna be honest with you guys.
I really don't think Bambu or "The government" cares all that much about how many Flexi Dragons you print or whatever.

It's always kind of a fall-down with these conspiracy things where people are worried they "They" will know what you're doing.

i get it man, i wear a mask and gloves whenever im opening my little enclosure, mostly because i hate the smell, and don't want to touch sticky shit.

but thats not what a lot of people are arguing, a lot of them make it into a political thing, because they already have a mindset picked out for that, while they lack any foundational info for the chemical/biological/regulatory properties of UV resin, so its easier to see what their side says about it than actually look into the reports on resin exposure.

same thing with the bambu printers, people see its a china machine sending info, and hook that info into their knowledge of china, and get alarm bells, even without knowing WHAT info its sending, or even how or why is being sent, and especially if theres an easy way to stop that info from being sent, like just not putting the printer onto a network.

honestly to solution is to just not buy bambu stuff if you're worried about it, there are SO many other choices.

same as with the solution to not wanting to get poisoned by resin is to just not get a resin printer if you're worried about it.

>>2994551
>Who the fuck cares? How is this information useful to anyone?
If it doesn't matter then why do they want it?

>>2994557
Because they can get it.
It's like if somebody offered you a way to find out what your neighbour was having for dinner every day. At no cost to yourself and with no way of him knowing it was you specifically that knew.

Some issue with bed adhesion, as anon said.
Clean your bed, if dirty, and maybe try applying some form of adhesive (I use a glue stick) or just increase the bed temperature a little bit.

>>2994565
It's hard to say exactly. I had a similar thing happen when trying a new brand of filament. The first few prints were fine then one with large surface area came out like yours. Turns out I needed to change my Z-offset. I ran a first-layer calibration and really pushed the filament down hard and that seemed to solve the problem.

>>2994573
If your filament is prone to warping, consider the location of your printer and the airflow around it, since it's an open bed. You're probably not printing ABS on that but even PLA will warp a little bit. If one side gets colder than the other side, that side shrinks and it might lose adhesion or otherwise cause issues. The pic you posted failed in two spots, on of then being on the edge so that could be cause for that spot.

>>2994565
Z offset doesn’t look to be the problem as it’s got a decent impression of the bed texture. I’d inspect the elephant’s foot to be sure. It could be that the bed mesh isn’t doing its thing properly (or you’ve somehow disabled it in the printer or slicer), perhaps it isn’t high enough density, or there’s grit or hairs under the bed causing it to be uneven. Cleaning the bed with a good soapy scrub is a good idea.

>>2994582
Not him, but isn’t that fine? A heavy rigid thing directly underneath the printer to dampen its movements, and spongy material beneath that so as to reduce vibrations travelling between the printer and the ground. I don’t really see how the table influenced anything, any resonance modes it has will be dampened by the paver.

>>2994585
I missed the part where he said what filament he was using. PLA for a PC case would be funny.

>>2994619
>heavy rigid thing directly underneath the printer to dampen its movements, and spongy material beneath
the issue is that the table will have fuck all dampening, but more importantly, i've had those tables before, and they RAPIDLY lose rigidity when shaken, and collapse, and that was with just a book and waterbottle moving a few times a day, cant imagine they would hold up to a printer moving and the added weight of a paver

>>2994540
>printers are sending every model you print to china so they can add spikes to your butplugs and sell your company secrets to the american government so they can tell disney and lockheed you're impinging their IP of guns and cartoons

Don't forget they're probably scraping every model you print for AI training too

But yeah the fact that they can remotely brick your printer for literally any reason they want is enough on it's own to ensure I will never buy something from them ever.

>>2994555
The difference is not having a smartphone today is a major inconvenience for almost every person, ie you don't have a choice about that, you're getting railed by smartphones whether you like it or not. But not every 3d printer company automatically spit-roasts you, you can buy from basically any other brand and not deal with it and still get a very good/equal quality machine.

>>2994561
>its why they made their stl host site too, to find out WHAT people are printing to sell more.

Fair but remember google and facebook and microsoft, etc, etc who started out as "just a company" that was looking to make money and were providing us with useful services for free? I'm sure they generally started out as just a company but then they start optimizing and that leads us to where we are now if left unchecked. So yeah it may just be finding out what people are doing with their printers so they can make printers that do that thing better, but it will inevitably lead to training AI's on your prints and flooding the world with modelingSlop and gaining more influence than any company should have in a healthy system if they are good enough at sucking you dry for information.

Its not nessicarilly what they learn that is dangerous, its what happens as a result. Imagine Bamboo gaining enough influence to push for laws and regulations in printers like we are seeing now.
