After adding MGN12H linear rails, the limit switch on the X axis has to be 8mm higher. That means, that the stock stepper pulley cover has to me removed to make more room for a custom limit switch adapter.
Pulley Cover :
I created two versions of the new cover.
- Cover that just clips on the heads of M3 screws with 5,4mm diameter
- → Aestethic look, but could fall of - not recommended
- Cover that will be screwed into the existing motor mounts with M3 screws
- → sits firmly, cannot fall off - recommended
There is a small slot to route the limit switch cable to the top.
Print orientantion :
The cover is designed to print without supports in the orientation shown below.
Adapter :
Credits to @Tzach adapter, i just shimmed the V nut a little to make it fit with standard M3 T-nut's.
