Sounds like you will have to use stepgen or something like it to generate pulses. If there is no feedback do you just mash it back against the stop and let the stepper stall for a while, then assume it's in place? Using an axis position is possible but because (I assume) it loses position when you change tools due to the above, the numbers won't represent anything "real". Also you would have to program A moves instead of M6. > Does EMC automagically remember the value between sessions or do I use the > external file for it to save the axis positions?

Your turret as-is seems like not a very good match for EMC's way of doing tool changes where they are separate from motion axes. But I bet you can make it work.
