Another option I've been looking into: Hall Effect sensors and linear arrays of tiny (~2mm) magnets. A simple relative encoding with end-stops...
Oh- jog control and reference holes for multi-sided (or 4-axis) milling, of course. I need to look into how the model interpreter module would...
Mods: Not sure whether this is best in interfaces (since it's designed as a hardware replacement) or CAM. Move as you see fit.
Ok, ready for another WALLOFTEXT? :D I've been thinking about this for the last couple of weeks, and I'm not really sure why it wouldn't be...
I'm in the process of creating more(!) threads (I like to write to organise my thoughts, I figure I may as well kill two birds with one stone and...
I did just have another idea though, but it might result in too-jerky movement: Using a laser that can provide very consistent power (+/-0.01%)...
^Ha! It really is a transporter chamber. Looking good! Looking forward to discussing it post-Faire. :thumbsup:
No, I've seen them before, but when searching for "continuous high torque servos" mostly RC servos come up. I'm just trying to find an industrial...
I'm looking at ball screws, too, because I don't want to deal with ACME/trapezoidal screw drive wear, which apparently happens all too quickly,...
Yeah, the availability of 110V also was supposed to be the other half of my original post but I forgot to put it in there. I can only assume...
That sounds similar to my general goals too! Yay! :D That's what I'm saying- because the arms aren't fixed like a gantry, but vary in their...
If you can pull the current to get 1.5kW+ from a circuit or two, just get a 110V VFD instead- LightObject sell those too. Doesn't matter what your...
I've realised that the OX X/Z gantry is exactly what I'm looking for on my build, but for the Y axis the platform itself will be the moving part...
This is true, and what I'm wondering about. For a screw-drive system, does it serve any purpose whatsoever? Could I go from 1/100mm to 1/1000mm...
I'm currently planning on going with a 2.2kW 220V VFD so I can use our unused dryer outlet and pull less current, from the US-based LightObject...
Thirded, a wiki would be excellent for storing information beyond build write-ups and software resources. That said, its scope could be difficult...
Would anyone consider there to be a speed or accuracy advantage to using some form of encoded feedback for the linear movements of CNC machines...
No worries, it's an interesting experiment with hopefully very practical results. And it looks awesome, more like an industrial robot than most...
(Thinking about it, it would be like a complex, miniaturized version of Matthias Wandel's Pantorouter)
Has anyone experimented with low-slop linkages in order to create micromills? I've never specifically looked for it, but neither have I come...
