I performed the skew calibration following the klipper guide and managed to square the xz and yz planes, but I can’t adjust the xy plane. I printed a 100mm calibration model, but when I try to print a calibration cube I get a greater misalignment than with the calibration model, 0.000920 on 100mm and 0.00288 for the 30mm calibration cube.
Even without compensation, I should get a smaller misalignment in a smaller piece, instead with the active compensation I get worse results for the cube. Also, the prints in X are shorter than they should be, both before and after compensation.
What could be causing this anomalous behavior?
TBH, I’m not at all a fan of this calibration stuff. The error introduced by
- Different extrusion factors / material properties
- Manual measurements
- Calibration model sizes
- Location biased effects of the entire motion system
is probably multiple magnitudes higher than what you are trying to correct. YMMV.
For some more detailed discussions on this subject, refer to: Dimensional accuracy problem
It is a problem very similar to the discussion mentioned, but I have calibrated the axes well, I have reprinted the calibration models and I get differences of 3 hundredths in the diagonals, but when I print a cube I get wrong diagonals and wrong length in X.
