Just as things are going well and you think you have the printer set up well enough to leave it alone, is when it wont play nice.
Started quite a long print job and left it running to come back hours later to this.
Some part job didn’t adhere to the bed and came lose knocking everything else about and finally falling off.
So tried again
This time filament jammed about an hour in.
So print test cube to check but whilst clearing the last job knocked off the belt for the bed allowing it to only feed in one direction.
