Hi There: I have an Ultmaker 2. I am experiencing a frequent and very frustrating issue where the Filament Tube pops out of the top of the bowden feeder. It does have the white plastic tube "holder" thing and the blue plastic retaining clip. When the tube pops out the filament just collects above the feeder and the extrusion fails. I'm using 2.85mm ColorFab PLA. Other than this issue the printer works absolutely fine. I general the issue happens during long prints. Any suggestions would be welcome!
