This CNC Z-axis motor mount for the SIEG X2 mini mill is designed with budget conscious hobby, educational, and light industrial users in mind.

Chris' Tips

Chris' Tips
To completely outfit a mini mill, you need the X and Y-axis kit and the Z-axis kit.

They both come with complete instructions. Here are the instructions for the X and Y-axis kit and here are the instructions for the Z-axis kit.

Installing the Z-axis kit requires that you increase the depth of the rack gear slot that runs through the spindle mount casting. This can be done with an angle grinder or other hand tools since your mill will be out of commission during the modification.

This Z-axis kit works fine the the belt drive kit.
