Clean the Bowden tube
Particles in the Bowden tubes can impede smooth movement of the filament. Clean the Bowden tubes at least
once a month, or after experiencing an issue with filament grinding. To clean the Bowden tubes, they must first
be removed from the printer.
Unload the filament first (see chapter 7.2 Unload Filament for help)
Lower the print head by moving the printer to the maintenance location.
Press Macro > Maintenance
You can alternatively also use PTFE to grease between the magnet and balls.
Remove the blue clip (if present) from the print head
Press the black ring (pneufit) down with your finger and pull the tube upwards away from the print head.
