Minimill CNC conversion WMD16LV X-axis adapter for NEMA23 direct drive

While I was making my CNC adapter plates with teethed wheels and belts, I discovered that not much exists that is ready to use for these conversions.

I am therefore also making direct drive adapter parts, to try this out.


This is the second piece I make for direct drive, for the X-axis.

The leadscrew has an outside part for the handwheel we will use for CNC that is 10mm, and some thread 8mm.  The thread is needed to be bolting the angular bearings (not meant for side torque) with some torque to the bearing holder.

If you do direct drive, you need a special coupler that can be split in 2. Then, you first mount one part on the leadscrew with some rings between the mill and the coupler part so that the nut can be placed in the coupler.  If the thread is too long, grind some off.

Then, put the rubber (with centerhole)  back in the coupler’s mounted part and push the other part in the rubber, so the coupler is complete.

Then, mount the printed adapter with already mounted Nema23 motor on the Y-axis and push the Nema shaft in the coupler.  Use the adapter’s right hand side working window to torque the connector on the Nema shaft and you’re done!

Should you want to have a handwheel as well, this is possible but you will have to buy a stepper with an axis that is both at the front as the rear. (this is called ‘double shaft’ but is actually a longer shaft, obviously.
