Little Emco lathe with some pittman servos... Amc drive that takes PWM+Dir.
https://www.youtube.com/watch?v=sUz5ZZyf2LU Of course caveats.. -with the input scale of 50800/inch - speed limited to about 35ipm. (probably fast enough for me) -Tuning has to be good - because if there is an oscillation - it oscillates faster than the computer can count.. Other than that. Seems like it would work ok... (a mesa card like the 7i92 would be way better) but this shows that you could get into basic closed loop servo control for the price of a printer port - you can still get them and pci-e is still a thing.. sam _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
