Unclogging the Asteroid Toolhead

Basics things to try first:


  1. Push the green lever all the way back (this loosens the tension completely). Then pull the filament out of the toolhead.
  • Use a pliers to get a better grip on filament to remove the stuck filament if you need to


  1. After the filament has been removed, try to load filament and push it through at the normal temperature then if it still doesn’t work increase temp to 290C


  1. If that doesn't work, carefully push a 2mm hex into the toolhead, from the top. The filament stuck inside may extrude out of the toolhead
