I've decided, due to cost and the fact I have two five foot racks, to dirve my gantry from both sides. This is necessary as I expect that my plunging z-axis will break the x-y plane. They are from Tourchmate and they are 24 pitch 14.5 degree power angle. I want to accomplich foam miling so speeds up to 50 inches per minute are not too fast. I am driving with a 254 Pacific Scientific M22 series stepper motor.
How does one tie the two sides together so that they don't work againts eachother.
Steve
