X-dolly-top for NEMA 23
thingiverse
This is a modification of the X-dolly-top of the R-CNC to mount a NEMA 23 motor, providing increased power for smooth Z movements. Problems with skips on Z moves are resolved by upgrading to this more powerful motor. To complete the upgrade, you'll need to add a Stepper driver TB6600 to the electronics and swap out the Pulley GT2 20t, with an inner diameter of 5mm, for one featuring a 6.35mm inner diameter. Tutorials covering this modification are available in both English and French on http://www.makerfr.com.
