@gorie said in Trigger height whitout Z probe:

Is that necessary if you don't use a probe?

That's a good question, I'm not sure. For a nozzle contact probe the X and Y are 0, but sometimes the Z value is still used. Such as the case if you used a feeler gauge to set the height on the bed, you would have G31 X0 Y0 Z0.2. If you are touching the bed directly, you would have Z0. I would assume that the P value would also be irrelevant, but you could still set it to some value just in case.
