X-dolly-top for NEMA 23

This is a modification of the X-dolly-top of the R-CNC to mount a NEMA 23 motor. I had problems with skips on Z moves, I found this more powerful motor addressed this. You will also need to add a Stepper driver TB6600 to the electronics and replace the Pulley GT2 20t, int diameter 5mm with one with a 6.35 int diameter.
