1. We only need the hardware, so remove the included wiring and pneumatic coupling. Unthread the attached coupling and pull off the heat sock to reveal the screws holding the assembly together Loosen the two indicated screw without removing them until the electronics slide out of their holes smoothly. Do not retighten

  2. Preheat your printer to 200-230 degrees celsius Remove the two screws on the fan cover, and set it aside on the gantry Consider everything under the cover to be hot until you set the printer to cool down
    • Preheat your printer to 200-230 degrees celsius

    • Remove the two screws on the fan cover, and set it aside on the gantry

    • Consider everything under the cover to be hot until you set the printer to cool down

    • Unscrew the pneumatic coupling and pull off the heat sock

  3. Repeat step 1 on the old heat block, loosening the indicated screws just enough that the electronics are loose in their slots Set the printer to cool down to prevent a thermal runaway when you remove the electronics
    • Repeat step 1 on the old heat block, loosening the indicated screws just enough that the electronics are loose in their slots

    • Set the printer to cool down to prevent a thermal runaway when you remove the electronics

    • Keep in mind that everything is very hot at this point

    • Hold the electronics by their insulation and gently wiggle them out of the heater block

  4. The old heater block is probably still hot enough to burn you at this point, make sure to hold onto it with something that isn't your hand Remove the two screws holding the old block to the frame, and use them to attach the new one

    • Remove the two screws holding the old block to the frame, and use them to attach the new one

  5. Holding them by the wire, slide the hopefully cool electronics into the new heater block Using the smaller Allen key, make sure the thermistor is sitting in its slot before tightening
    • Holding them by the wire, slide the hopefully cool electronics into the new heater block

    • Using the smaller Allen key, make sure the thermistor is sitting in its slot before tightening

    • Tighten both screws just enough to hold the cartridge and thermistor wires in place; pull on the thermistor wire just enough to keep it under the screw head while tightening

  6. Reattach the pneumatic coupling and heat sock, making sure that the Bowden tube is pushed all the way into the block to sit snuggly against the nozzle. Reattach the fan cover
    • Reattach the pneumatic coupling and heat sock, making sure that the Bowden tube is pushed all the way into the block to sit snuggly against the nozzle.

    • Reattach the fan cover

    • Make sure to relevel the print bed before resuming printing, as slight differences in the placements of the heat sinks and nozzles might change the print height
