Not yet, but I certainly intend to try once my laser's (405/445nm) up and running. Would make both packaging and costume-making details and...
A decent idea for the base, perhaps, where the sheer surface area counters most other issues, but I wouldn't rely on that technique for perfect...
If it helps anyone, if I was going to try to do this without a complete separate machine to make the parts on, I'd use the following sequence. I'm...
Like I described on the build page, it's a great machine for what it is, it's seen some pretty heavy use for me and just keeps on trucking....
Three-fifty?! Per axis that seems pretty low for the power required, and for all three seems like magical wonderland pricing. Where'd you find...
Hmm. Perhaps there are discussions elsewhere online about this kind of marginal decision-making. Obviously the answer is servos, as it usually is,...
That sounds a lot better than 275:1 to me! It's certainly a balancing act, especially given that as you get into higher torques, it's usually...
Yeah, inertial matching of motors and axes is like impedance matching of power electronics or audio systems. You don't HAVE to do it, you can...
Fixed the images! I think the server ate them, but should be good now.
16mm ballscrews are definitely a lot heftier than the pictures make them look! As for steppers and spindle: 1) For primarily machining aluminum,...
The laser is far closer to completion than its build thread would suggest, there are a pile of mill conversion components sitting on a bench, and...
Current thoughts and considerations: Motors: Geared NEMA 23s would likely be higher acceleration, but I'm somewhat dubious on their relevance...
Rob Taylor published a new build: A proper CNC mill conversion. But quite small, with my trademark idiosyncracies. Read more about this build...
Yeah, even if the 1000mm length is just the screw and not the machined ends (which I'm not 100% sure about), you also have to subtract the length...
What are you trying to turn? The ends define the means here. When you say 3 axis lathe, do you mean X-Z plus a Y, mill-turn style? A moving...
Probably because it's a link to a PM.
Oh, that signmaking stuff? Seems great, I'm surprised we don't see more of it around in a variety of places. Maybe it's super expensive.
Has he been around a while? I wanna say I bought something from there (through eBay?) when I still lived over there. If not, it looks like the...
I wondered about that too- it was my very first thought, then I second-guessed myself because I assumed there was some reason no one was already...
Seems like urethane should be a logical option- available in a variety of hardnesses, easy to both precision cast in silicone and machine, tough...
