Hi, my printer is a self made CoreXY with moving bed, which is rail guided at the backside.
With BLTouch I perform autolevel (3 points , close to 3 adjusting screws) as well as distortion correction, which works well except one issue:
Printing test lines (Layer height 0,3, extrusion width 0,6mm) I found, that the resulting line thickness is 0,3 at the front side of the bed, and 0,2mm at the back side.
Probably bed bending during printing causes this issue.
So I tried to set bendingCorrection_A and _B to 0.1mm in EEPROM setting. No more G32 or G33 or reboot.
The result was: no effect of bending correction.
My question: Is BendingCorrection a good way to solve this issue and , if yes, do I need to more steps to activate bending correction or should it be enought just to change EEPROM settings and reprinting my test lines.
Thanks in advance for your help!
