I just had to figure out how to use independent motors for an x axis gantry with separate homing for each motor. gantrykins is the solution to this. http://linuxcnc.org/docs/html/man/man9/gantrykins.9.html it allows you to develop 2 independent axis's and then tie them both together into one axis that drives both stepper drivers you should be able to have a different scale for each of the 2 axis's too. check out the code uploaded by decoyable on 10 april 2013 on the following thread:
http://www.linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/25541-implementing-gantrykins?start=20 they create an "A" axis then tie that axis together with one of the main XYZ axis' for a gantry. hopefully these 2 references will help you as much as they helped me. thanks.
