This document will outline the steps necessary to clear a
clog in the heatsink tube assembly caused by the filament
bulging up inside the tube. If the filament becomes clogged,
neither loading nor unloading will be possible. Tube clogging
can occur by either using an old filament that’s kept in the
open for a longer duration or from 3rd party filaments with
lower transition temperatures.
Tools Required:
• Scissors
• 2mm Hex bit or Hex wrench (Allen key)
• 2.5mm Hex bit or Hex wrench (Allen key)
• 3/32 inches Flathead bit or screwdriver
• T10 Torx bit or screwdriver (no longer than 4 inches)
