Thanks everyone for your help with the motor controller question. It cleared up a lot of confusion.
Since I'm not using EMC for CNC, I'll have to program it to do what I want. I looked at Galil, and they had a whole set of (arcane) commands to say "move this many encoder counts at this velocity" and things like that. What's the EMC equivalent to this? I looked over the user manual pdf and couldn't find any information. To give you guys more context...I'm trying to build a haptic mouse scrollwheel. Suppose you're trying to find some text in an 100 page document, and the program finds 20 occurrences. You start scrolling, and the motor attached to the scrollwheel makes you feel a bump each time you pass an occurrence of the word. Maybe you might want to have feel different "textures" for different documents. This might help the blind. I want to scroll at a constant velocity, so I give the scrollwheel a flick and the scrollwheel turns at that velocity indefinitely. Also a mode like a spring would be cool: the scrollwheel "wants" to be at a certain position, and the more you displace it from that position, the more force it exerts to get itself back to that position. Any advice on where/how to start? Can I do this all in g-code or would I have to be lower-level? Thanks, Gerry ------------------------------------------------------------------------- Take Surveys.
