And in that description it says no other axis can be moved while moving a locked axis. And if thats true, then this whole idea is dead in the water and sunk. I want to use this to run the BS-1 while cutting a spiral gear so at minimum, it must move WITH X, and maybe Y too depending on the cutter. Hardware oneshots in the cable it is then. If that doesn't work, buy a box of 2M542's unless there is a cheaper alternative. Suggestions welcome as I already have a 24 volt supply for this. Or a 48V I can turn down to 42.5. That is what I'm powering the Sheldon's Z with these days, and that 3NM 3 phase stepper/servo fairly flies. And someplace on a truck, is a 2NM version that will be driving the X axis about 2 days after it falls out of the truck in front of my place. A 3NM on the rear of the aspron won't clear the bed, but a 2 will. ;-) But I'll gain another piece of SS pipe for cableing on the right edge of the carriage too. Thanks Andy.
