Yes, with the EMC you can use the Kulaga/Mauch DRO card and a stepper
motor driver called smdromod.o. You need to add encoders to your motors
or leadscrews.

I don't recommend using linear encoders -- thinking that you can get
around backlash problems -- because you will create problems with motors
dithering across the backlash. Backlash comp was not written to cure
this kind of problem. In fact it makes it worse.
