Compatibility

  

Installation:

  1. Observe slight inside taper (chamfer) of PTFE tubing. This inside taper is the top. This helps guide the filament.
  2. Position jam nut almost completely threaded onto the knurled adjuster or Y adapter.
  3. Screw in the adjuster or Y adapter assembly into the heat sink by hand (no tools) until some resistance is felt. The resistance will be slight compression of the PTFE squeezed between the heat break at the bottom and knurled adjuster (or Y adapter), then stop (see next step).
  4. No tools, turn 1/4 further to slightly compress the PTFE tube. We estimate this rotation and end somewhere 1/4 turn or slightly further.
  5. Then use the blue SeeMeCNC hotend spanner wrench (included) or needle nose pliers to firmly tighten the jam nut to the PCB. 
  6. Install the included nylon PTC locking clip(s)
  7. Seat the bowden tube again (after installation of the locking clips).
  8. Finished
