Your X and Y offsets have changed - we talk about the Z offset all the time, but the printer also needs to know the distance from the nozzle to the sensor in X and Y. I don’t know if that can be set from the screen or if you’ll need to recompile your firmware.
Hi @VagabondElf yes, you would need to set the M851, at least this is how I generally do it. If you connect to your printer via pronterface you can set them manually.
