XYZ probe

Oke I want to make my own z-probe. I bought an aluminium staff 3mm thick and I got a crocodile clamp.
So now the wiring, do I connect the wires just the same as an endstop? And then I have to connect it to the Z-minus on my MKS Sbase board?

It depends a little on the firmware. But in theory, you connect the bit to ground and the plate to S on the zmin. Test with M119 first. Then you can do G28 Z and it should stop when it senses a closed connection. Then you need to use G92 to adjust for the thickness of the plate (G92 Z3).

Oke I got the Rambo dual endstop firmware adjusted a bit to work with my board. I will try it…

Yes it works…

But also this time in CNCjs, I had to type M119 3 times before it works.

Edit: I think I found it… it’s case sensitive.

My clamping system is ready… I’m doing the coasters 1 by 1.
CNCed out of Birch plywood except for the handles, they are normal plywoord. As I couldn’t get that thin birch plywood at my local shop. The tubes are 15mm aluminium.
