#SOLVED
I want to home Z at max before doing G32 using 3 motors with sensorless as endstop.

I can home Z fine, but it stops when one motor triggers. Can I now home the other two axis after this and how? I see how to do it with endstops but of course I want something not described.

@pro3d what M574 command are you using? S3 should stop when the first motor stalls, whereas S4 should run each motor until it stalls.

Oh.. I was using S3 yes. Thanks, I just configured ZUV independently and got it working but that is not necessary using S4?

That's right, not necessary if you are running RRF3.
