@hardware-crash said in Anycubic Kossel plus - Bed Leveling errors with BLTouch:

I think i might have found a point that could have caused the problems with the BLTouch.
The mounting plate for the BLTouch (found on thingiverse), which is screwed to the fan collides with the push rods when it comes near to the towers of Y & Z axis. I commanded the effector to the positions directly under the Y & Z towers and the rods push quite hard against the BLTouch mount. Could this cause autocalibration to fail or wrong values ?

Yes, in a couple of different ways.
