Step 2 Attaching to S1

Remove the inlet Bowden tube from the S1 by pressing down on the blue release ring while pulling the tube out.

 

Step 3 Attaching the Mount

Slide the mount onto the side of the gearbox, ensuring it is aligned properly and fits securely in place.

 

Step 4 Insert the New Inlet Tube

Insert the new inlet tubes by pressing them through the small hole in the mount and into the blue fitting. 

Continue pressing until the tube reaches the hard stop and is fully seated in the gearbox.

 

Step 5 Attach the Filament Cutter

With the slanted end of the Filament Cutter facing the back of the S1, place the rear groove of the cutter into the mount, then rotate it forward until the front clicks securely into place.

 

Step 6 Insert Filament Cutter Tube

Press the locking tabs on both sides of the Filament Cutter, then insert the new tube until it is fully seated.

 

Step 7 Repeat on Second Extruder

 

Step 8 Load filament and Begin Printing

To load filament, simply feed it into the Filament Cutter until the S1 detects and begins loading.

  • Hold the inlet tube to prevent an accidental cut.

 

Step 8 Resetting the System

  1. Remove the end of the fialment from the cutter.
  2. Ensure the cutter is fully retracted to its upward position and clicks into the detent.
  3. Reload the next roll and continue printing.
