NewFatMike posted:I come bearing news of other Weird Hobbyist Machines, this time the Langmuir MR1. It’s a gantry based 3 axis mill that’s actually looking like it does pretty good work: I keep seeing ads for that thing and thinking “hmm I want one of those” before coming to my senses and remembering that I have 3 mills and 2 lathes available to me to use any time at work.

A Wizard of Goatse posted:Quick question in case I'm missing something that makes this make sense: is there any good reason to have like twice as much ballscrew as rail on an axis, or was this guy just a lunatic who loved vast expanses of useless metal flailing around every time the gantry moves It might be something as simple as the original maker not having the proper tool to cut down the ball screw down to length. I had to cut one once and it quite hard on the outer layer. If you don’t have a cold saw with the proper blade I can see just skipping it.

A knife to the gut! (I refuse to edge find anymore but that’s because I have a nice haimer 3D taster and renishaw probes on everything)

I feel like ATC is a place on the machine you don’t want to cheap out on. I can’t figure out exactly who this third party toolchanger is for. A for-reals production shop will kill this thing pretty quickly, and a hobbyist (the bane of online machining forums) isn’t under time pressure, and can just manually change tools. I guess some kind of cabinet shop that is running on a serious shoestring budget is the target market for this, but a shop like that is hell on earth and I advise anyone to stay far far away. Edit: I fully recognize the irony of posting like that in the “Hobby CNC” thread tylertfb fucked around with this message at 23:30 on Jan 8, 2024 |

CarForumPoster posted:Relatedly to the Linux CNC path planning discussion, I wonder if there was some interpolation based on look ahead that caused the machine to calculate a trajectory point outside the soft limits. The tip of the engrave tool is doing 0 SFM anyway, may as well save electricity by having the spindle off.
