Thank you Gerry and Eric.
I am going to look into turboCNC.
I hope I am not asking to much of these boards. I don't know how much the torque drops off at higher rpms. I checked the stats on the ball screws and with the numbers from the company, I only need 1.75 in/lbs to drive 50 lbs. I am not sure how to convert in/lbs to oz/in. If it is as simple as multiplying by 16, I am looking at 28oz/in. This seems hard to believe and I don't want to use the motors at there peak level.
Was I wrong about Gecko boards needing 1 per axis. If I was wrong I might be able to fit servos into my budget.
Why do you prefer Xylotex over FET-4?
Can you run bipolar motors from a unipolar board?
