Paciente8159's CNC probe

This is my take on a CNC probe with some special features which are:

No electronics. This probe has no special built in electronics, contact PCB nor electronic circuit (you can add one it if you want to)
Everything can be either printed or purchased at any convenience store
No tuning. This one relies on small magnets that perform a constant and even downforce. No need to to tune the spring strength
Different types of tips can be used and changed easily (ball, conical, etc)


I've tested my probe and the repeatibility test yield a 6 microns (and that is because my CNC resolution is 6.25 microns soo it is good :-P)

Additional materials needed

3 x 5mm diameter 16mm long shelf pins
6 x M4 domed nut
24AWG stranded wire (the internal conductors of an Ethernet cable will do)
1 x M4 nut
2 x 20mm long M4 threaded rod (one is screwed to the probe top lit and and the other to the contact part holding the shelf pins and half the magnets)
6 x 5mm diam
