Since adding a laser Z-axis to my MPCNC toolkit, I was looking for a quick way to swap between my CNC and laser Z-axis. I originally had all of the wires with separate connectors to make it hot-swappable and I ended up breaking a few wires at the connector due to the movement of the Z-axis.

After a few trial and error attempts, I ended up designing a new motor mount for the Z-axis to hold a DB9 connector with all the supporting wires for swapping Z-axis assemblies with ease.

Most of the weight of the cable is being held up via retractable badge ID holders which doesn’t add unnecessary strain to the Z-axis core.

This modification pairs very well with my MPCNC Tornado dust collection and air assist setup!
