Has the cable for your Z-Probe come loose?
Try this replacement part.
When I unboxed my Shapeoko Probe, I noticed that the cable had a strain relief sleeve, but it had popped out of the slot in which it was supposed to register. The grey 3D printed cover plate set into the bottom of the unit was designed to give a large volume for the back of the strain relief. I guess that seemed like a good idea, maybe they used a slightly different cable originally, but now it just allows the cable to fall out and increase the chance of the soldered joints to the internal PCB breaking.
I modelled this replacement in Fusion 360, using dimensions from the original part and from the slot in the side of the probe. I've added a little extra clearance on the holes for the M3 machine screws, as most printers close up small holes a little.
It's best to print this at high resolution, maybe dynamic layer heights etc, if you have the option, as the filler section at the top is a little tricky to get right, with it being so small. If you can slow down at the end of the print, that would help.
Infill can be tiny, I used 5% gyroid in Cura, with 0.15mm layer height, UM Tough PLA, no support.
The black part shown was actually a slightly earlier version, printed with the 0.8mm print core and with corner fillets that were slightly too sharp to fit. It is shown only for general comparison with the OEM grey part.
The little tower that sticks out of the top is tricky to print, if you can slow down, add resolution or increase cooling for that last section, go ahead.
