Maintenance
Press the black ring (pneufit) on the feeder/extruder motor and pull out the tube.
Cut off a small piece of sponge or ball up a piece of tissue.
Insert this into the feeder end of the Bowden tube and push it all the way through the tube with a length of the
filament.
Place the tube back in the printer, watch the correct sides of the tube on the correct spots in the printer/print
head. (slightly chamfered outside is the print head side of the tube)
