Updated mounts for CNC homing switches

Project history

  1. Previous project: 4th axis homing sensor
  2. ATC upgrade
  3. current posting
  4. next step
  5. Next project: designing a chain link tool library

A while ago I posted some simple, 3D printable mounts for homing switches on my Chinese CNC6040.
After upgrading to a smaller USOVO ATC (automatic tool changer) spindle, the Z-Endstop no longer fit.
Formerly it would push against the upper spindle mount but this spindle only needs a lower mount.
So I added a 3D printed helper part to my design.

 As you can see, it is still 7mm too long and I will change that next week.

Update: currently printing the fixed version....

Update 2: Improved part is done and will be mounted next weekend.

Here are the other homing switches.

 The inducting homing switch for the A axis still needs to be mounted again.
