Our Flashforge, everytime we try to set off a print, even tried and tested ones, or try to set the printhead to ‘Home’ it tries to push past the end stop and judders till we switch it off.
Any ideas, or has it gone plain nuts.
It’s only a few months old, still using the filaments that came with it
Was it fine and just started, I am guessing? If so check the cables to the stepper motors. Swap them around and see if it helps or changes anything. I just had one go bad and it did the same thing except it also did it mid print. This is not a visual inspection.
