Repetier Host and Firmware for PCB Mill

mezeq79

Hello, my name is Mariano.

I finally set up my prusa P3 steel extrude plastic really well and make my modifications to mill PCBs.

My problem is now how to use autolevel Z axis for PCB.
I saw there are some SW that use electrical conductivity in the end mill and the PCB to test surface. Such as Leveller and Sw used in Cyclone Project.

My question is, does Repetier-firmware allow me to use any of this conductive surface testing probes?

I tried milling and it does some "air mill" because of unleveled irregular PCB surface.

Any ideas on how to use it?


I was thinking in a "primary" solution, that would be to use a different "endstop" for autoleveling in CNC mode.

Using (until now) unused ZMax Endstop in my 3d printer to connect crocodrile pins to end mill bit and PCB to send signal using Z Probe as if it were a Normally Open mechanical endstop.

Is that possible?

Thanks in advance

If that gives no short you could do so. Set mech. endstop so pullup is high. Connection would drag it to closed and return the hit signal for the endstop.
