>>2944099I got a question for machinists Why is it that you guys can cut titanium to fractions of a human hair width with crazy amount of repeatability But none of you guys seemed to make a marriage last? How’s it feel knowing that you see a Burned in CRT screen on a machine control that’s going to be in a scrap yard after you die more than you see your children?
>>2944099>Ignore SiegThat's some good advice right there...
Has anybody here tried out a desktop CNC machine like a DMC2 or Carvera? I know they're less than ideal for steel, but the idea of being able to fabricate metal parts in my garage is very appealing.
>>2944128HAHAHA OMG HOLY SHIT WOWTHIS GUY REALLY HAS YOUR NUMBER LMFAOAND THE WAY HE HITS ENTER TWICE AFTER WRITING ONE SENTENCE ON A LINE IS JUST THE ICING ON THE CAKEHAHAHAHA WEW
>>2944326>Has anybody here tried out a desktop CNC machine like a DMC2 or Carvera?Not personally, but i was witness to people attempting to use them.>I know they're less than ideal for steelWon't keep you from buying one and trying it.>but the idea of being able to fabricate metal parts in my garage is very appealing.If you're fine with aluminium and it looking like a rodent chewed it out, sure, you can "fabricate" metal parts with that.Now go buy one and be disappointed. Why did you even ask.
>>2945184because he was hopingyou're right but there's no need to be prissy about itadopting a more positive, less sarcastic outlook will fortify yourself as well
>>2944326Me being me, I'm waiting for those spark generators from rack robotics to get some reviews then I'm building a wire EDM. Safest machine to use as long as you don't touch anything.

has anyone dared to try this thing
How much does a brand new lathe and mill depreciate in value?
>>2945859Only at least a few tens of thousands of people. There's reams of information on the 7x lathes out there.I used to have one. It was okay. My biggest complaint was that the gib on the...either the cross slide or compound, I forget which, fit terribly in the dovetail. So badly that it allowed the tool to suddenly tip downward by like a full mm in a "heavy" cut. It was usable if you only ever took cuts light enough to avoid that problem, but that made things painfully slow (not to mention surface finish issues). Apparently that's not too uncommon a problem and I planned to fix it, but I scored a great deal on a 2000lb 14" lathe with fixable gearbox problems and sold the mini.Would I buy again? Hate to admit it, but yes. Take that with a grain of salt, though. Now that I have other, much larger equipment, it's far easier for me to fix any problems it has than someone who's stuck with the mini as their only machine tool. Also, I bought my 7x14 when the more "premium" versions were like $800 including accessories. HF is currently selling the smaller 7x12 for that much and I can't even tell if that comes with a drill chuck for the tailstock.
>>2945859My work got this vevor lathe as an impulse buy and even as a cheap stuff enthusiast I think it was a mistake. I picked it up for free from them a bit ago and honestly will probably never use it for anything.
>>2945850burs are easy to fix, dirt can be cleaned, even if they are annoyingi usually consider them unfinished hardware
>>2945912yep sop. took about an hour to clean up. its my 5th chinkchuck so far. the best was a 6" i bought circa 2007. the jaws are glass hard and it clamps within .0015 across the full rangei have to murder another old chuck to cannibalize the d1-6 backplate before i get to assess the true functionality of this one
>>2944326did you order 1 yet?
>>2945184Nah fuck this guy, those cavers airs take some monster cuts… guy I know has a corn cob rougher on his, and a 14” 1” 3 flute finish mill to do tool steels a lot of horsepower and just uses 120v super worth it
>>2945850it only appears to be the 3rd chuck that has lived on this backplate
What's the best free offline CAD software? Have done 2 gymnasium courses with Autodesk inventor and I'm doing one with solidworks right now, but since they're p2w i most likely won't be using them for hobby purposes.
>>2949378freecad 1.0 is kinda good, and 1.1 is about to go out this month probably, and its supposed to get all the good stuff that couldnt make the cut of the 1.0
Taking a community college machining class, made my first chips today. Looking forward to really getting into it next week.
>>2949972I look back with fondness at the time in my life when that was me. Make some friends anon, don't stress too much and enjoy it.
>>2949997Basically what I'm doing, this class is a side dish to a welding associate's so I can actually have fun with it - though honestly I find machining way more interesting and enjoyable than welding, and would probably switch majors to it, but the job prospects are a lot worse afaik. The friends part is kinda iffy, I'm friendly with a few guys in my classes but they're mostly zoomers straight out of high school and I'm old enough that it wouldn't even be that weird for me to be their dad. My teachers are more like people I'd hang with though, and weirdly my welding instructor is a girl a year younger than me and totally my type which is pretty awkward, it's a lot of work holding myself back from hitting on her.
