When I use the Auto Level feature on my Anycubic Kobra 2 Neo, it works fine until it gets to the calibration part where the extruder goes over the sensor. The print bed vibrates and I get “Calibration Abnormal” on the screen. I’m not sure what the problem could be, adjusting the belt tensions doesn’t have any effect.
I’m not familiar with that printer so this is a shot in the dark. I assume that the sensor and the extruder don’t touch???
