Das geht nicht auf die Problematik bei Deltas ein.
Ist ja auch in der Klipper Doku erwähnt

ZitatAutomatic vs manual probing
Klipper supports calibrating the delta parameters via a manual probing method or via an automatic Z probe.
A number of delta printer kits come with automatic Z probes that are not sufficiently accurate (specifically, small differences in arm length can cause effector tilt which can skew an automatic probe). If using an automatic probe then first calibrate the probe and then check for a probe location bias. If the automatic probe has a bias of more than 25 microns (.025mm) then use manual probing instead. Manual probing only takes a few minutes and it eliminates error introduced by the probe.
If using a probe that is mounted on the side of the hotend (that is, it has an X or Y offset) then note that performing delta calibration will invalidate the results of probe calibration. These types of probes are rarely suitable for use on a delta (because minor effector tilt will result in a probe location bias). If using the probe anyway, then be sure to rerun probe calibration after any delta calibration.

ZitatAlles anzeigenLocation Bias Check
Some probes can have a systemic bias that corrupts the results of the probe at certain toolhead locations. For example, if the probe mount tilts slightly when moving along the Y axis then it could result in the probe reporting biased results at different Y positions.
This is a common issue with probes on delta printers, however it can occur on all printers.
One can check for a location bias by using the
PROBE_CALIBRATE
command to measuring the probe z_offset at various X and Y locations. Ideally, the probe z_offset would be a constant value at every printer location.For delta printers, try measuring the z_offset at a position near the A tower, at a position near the B tower, and at a position near the C tower. For cartesian, corexy, and similar printers, try measuring the z_offset at positions near the four corners of the bed.
Before starting this test, first calibrate the probe X, Y, and Z offsets as described at the beginning of this document. Then home the printer and navigate to the first XY position. Follow the steps at calibrating probe Z offset to run the
PROBE_CALIBRATE
command,TESTZ
commands, andACCEPT
command, but do not runSAVE_CONFIG
. Note the reported z_offset found. Then navigate to the other XY positions, repeat thesePROBE_CALIBRATE
steps, and note the reported z_offset.If the difference between the minimum reported z_offset and the maximum reported z_offset is greater than 25 microns (.025mm) then the probe is not suitable for typical bed leveling procedures. See the Bed Level document for manual probe alternatives.
