My ultimaker 3 will start printing fine, but then when it goes to swap filament usage from 1 to 2, it first goes to slam itself into the back right corner. It attempts to push into the frame, making a loud clicking and banging sound. It then does actually swap the filament, but in the process the bed gets pushed down, unleveling it in the process. It will then start extruder from print core 2 but at about 6 mm (1/4inch) off the build plate, and then the print is ruined at that point. I have tried releveling, changing slicing files, changing filaments, shrinking the file, and checking the belt tension, but nothing seems to fix it. It does work if I just use 1 printcore. Does anybody have any experience with this issue?
