Bad Bed-leveling/Z correction

trejbal113

Hello, I have a question:
(I have repetier v1.0.1) When I use the G32 S2 for leveling, everything will work fine. The correction works well, but if the extruder goes to Y> 90, the Z axis will begin to rise a lot. About two millimeters rises. But the bed map does not answer that. Why is it?

There is my configuration:

And there is my bed map:

Repetier

First disable autoleveling to see if it comes from autoleveling. It could also come from distortion correction (G33). You can also disable G33 and see if it still happens then with both disabled. Then it could be some strange hardware error causing signals to come to Z stepper for Y > 90 also that sounds very unlikely. Would more bet on distortion correction. Normal correction would happen with equal amount for a move and not start at some point.

Ok. I disabled autoleveling, but the problem remains. What shall I do now?

Repetier

Disable distortion correction as well
M323 S0 P1
to see if it comes from that.

Problem solved! Thank you very much for your help. By the way, what is G33 used for?

Repetier

That is distortion correction. used e.g. if bed is not planar or for deltas with nonlinear moevement not calibrated 100%.
