Throws a "Move out of range error"

[pi3123]

Describe the bug Move out of range: 7.732 48.634 -3.452 [0.000] Move out of range: 7.732 48.634 -3.452 [0.000]

Throws this error when running the PRTOUCH_PROBE_ZOFFSET

To Reproduce Steps to reproduce the behavior:

1. Run the PRTOUCH_PROBE_ZOFFSET

Expected behavior Get z_offset

@pi3123 You might need to adjust your position_min under the [stepper_z] section. I have mine set to -5 to ensure I have enough room to go negative when probing for the z-offset of the nozzle. I think something in the range of -3.5 to -4.0 should be more than enough.

That works! But now the z offset is much higher than the perfect manual one I got. I got a 0.735 and its giving me 0.913. Anything I gotta configure?

Not really, my experience is that z-offset with this version of prtouch is "good enough" but not perfect and definitely lower (and there's no code publicly available to use newer version).

For example my auto z-offset is 1.982 but Benchy bottom letters are barely visible. If I change to 1.765 letters are much better.

So there're three options:

• use auto Z and don't change, most prints will be OK provided you don't get completely bad value,
• use auto Z to measure and then correct it until you find a perfect one,
• use auto Z and compensate in g-code by small amount

@pi3123 Are you probing the Z-offset with the bed and extruder heated up to printing temps? I've found that, due to thermal expansion, the Z-offset will be a bit too close if probed while cool.
