I have an Ender 3 a 3DTouch, with the SKR Mini E3 1.2 board.
From one day to another the probe started producing this pattern, where the right side of my bed (5x5 mesh, tried with 3x3, 7x7, all produce the same pattern) just drops by a significant amount. The bed is the Creality glass bed. I tried switching it back to the stock Ender 3 plate (non-magnetic), but no physical sign of this drop can be seen by the eye.
Probe testing with
M048 usually gave me Range ~0.005, and standard deviation between 0.001-0.0025 both in the problematic part, and any other part on the bed.
What could cause this problem?
