I was wondering if anyone had come across an issue with the XY offset file becoming corrupt. Updating the firmware doesn't fix things, It'll always print this strange pattern. That's actually only half the pattern, I'll continue with the X rectangle at the top but tries to draw it too far back past the limit and starts grinding the gears a little. It always prints models fine, there's just no way for me to set the offset.
Ultimaker 3 with firmware version 22.214.171.12400331 (most up-to-date at the time of writing)
