As long as someone has already written the modules to control a

Yes, I think that it should work, it is simpoly a configuration issue
for EMC.


Our older cnc lathes with gear boxes require a M41 or M42 command to switch gear ranges.
Perhaps you could implemnet something similar where the command emits an output you use to
shift the sheave. IRRC M41-44 are typical gear change M codes.
