@jay_s_uk maybe you find some solution there: https://duet3d.dozuki.com/Wiki/Gcode#Section_M556_Axis_skew_compensation

@jay_s_uk i's not a 3D-Printer but a Duet controlled machine. I can't go int details.

The kinematic is configured as followed:

M669
Kinematics is Cartesian, no segmentation, matrix:
1.00 0 0 0
0 1.00 0 0
0 0 1.00 0
0 0 0 1.00

@dc42 Thank you for your suggestions.

Indeed, the issue was caused by motor currents inducing some noise in the sensor cable.

I followed the procedure I described above and then simply sent an M18 command to disable the motor, and it worked fine. However, when I sent an M17 command to enable the motors again, the issue reoccurred.

I’ve since changed the wiring, and now everything works perfectly.

Thank you so much for your help!
