Good thought.

I did have a thought about direct driving the x and y with a stepper. However, after looking at other conversions it seems that everyone has done belt systems rather than direct drive, and only direct drive on smaller machines. All that I could think of for being an advantage would be that you would increase the available torque. Im not sure how much torque is required however im sure that a single Nema 23 3Nm stepper would be suitable for operating the axis'.


If anyone has any some thoughts on this, again any suggestions would be sooo helpful.
