Gruess Gott!
I've got printer with Prusa-like kinematic, mechanic probe with optical endstop (BLtouch self made). I print on not very flat glass. The maximum bed height distortion is 0.2 mm. In the firmware the autoleveling with bed leveling method 1 is enabled with bed correction method 0 and distortion correction as well.
Once in a while, before printing with new bed temperature (ex. 100C for ABS where I expect bigger bump at bed center after printing at bed temp 60 C for PLA) I run the script to renew the rotation and distortion matrix:
My first question is: is it normal?
The second: wouldn't it be better to disable the rotation correction and enable only distortion correction matrix?
Thank you!

Once in a while, before printing with new bed temperature (ex. 100C for ABS where I expect bigger bump at bed center after printing at bed temp 60 C for PLA) I run the script to renew the rotation and distortion matrix:
- M322 S1
- G33 R0
- G28
- M140 S%(bed_temp)s
- M190 S%(bed_temp)s
- G28
- M322
- G32 S2
- G28 X Y
- G33
- G33 L0
- M140 S0
- G1 X100 Y120 Z30 F15000
After that I print with just homing all axes.
When print starts and printhead goes from Z-max endstop down to the bed X and Y motors make small steps. I think they are correcting the rotation. After that I print with just homing all axes.
