CNC Spindle Z probe

thingiverse

This is a Z probe for a CNC spindle. You mount it in the collet, just like any regular endmill, and connect the wires. I designed it specifically for bCNC Autoleveller. Required parts: 1x M3x10 1x Microswitch (the small one) Wires Assembly: Screw the bolt into the hole in "Body 1", secure with a bit of superglue so it doesn't turn loose. Solder the wires to the microswitch, then pull them through the rectangular hole. Glue the microswitch firmly in place. Filing down the edges helps a lot. I also plugged the hole by filling it with some extruded filament, you can also use hot glue. Thread the cylinder ("Body 2" or "Body 3") onto the screw. The cylinders are designed to fit 4mm and 6mm collets, if you need another size you have to design one yourself.
