EZABL sensor mesh compensation

Ladusse

I add the EZABL sensor on my printer. I can home the machine but as soon that I try to run the mesh compensation it won't work, I define the area and when it go to the first point it crash into the bed. Here is my config. Any tips?

@Ladusse There's a good page on setting up the EZABL here: https://support.th3dstudio.com/helpcenter/duet-board-setup-information/

Can you send M115 in the console, and post the response, to show RRF version and hardware? Also send M98 P"config.g" from the console and check for any errors (I think you define 'e0stop' twice, once as a filament endstop, then again as a filament monitor).

Check that your offsets are correct, and the probe works correctly: https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_testing

@droftarts, the Z: low end Z probeERROR: pin 'fan1' is not free line look weird to me

You're trying to use the fan1 pin twice.

@Phaedrux I fix the fan and now it's working. Thank
