What is the problem?
I just upgraded my Ender 3 mainboard to V4.2.7, and when I went to test it out I used the bed visualizer, but as it moved it ignored the limit switches so it made horrible noises and made no progress.
What did you already try to solve it?
Haven't been able to find many solutions at all. I tried plugging in the pi after the printer was running as suggested by someone else, but that was ineffective
Have you tried running in safe mode and if so did it solve the issue?
