I intend to use the unused z axis on the controller. The motor shafts
are single ended and I thought about putting them shaft to shaft with
a modified timing gear between. This would be the x and z axis and to
move I would have to direct the motors to move x -a and z +a and to
reverse x +a and z -a (a being the distance required to move)
Does this sound feasible?
I am not sure that the maxnc controller that I want to try this on
could run 2 motors from 1 output?
