Step 1: Unload Filament and Remove Print Head
To begin, follow the existing guides on our wiki for unloading the filament and removing the printhead from your machine. Once the printhead is removed, bring it to a workbench to facilitate the replacement process.
Step 2: Cut Zip Ties
Inspect your printhead for a zip tie on the part cooling duct. If your printhead is a newer model with a zip tie, cut it to release the Hotend cables. Older printheads may not have this feature, in which case you can skip this step.
Step 3: Disconnect Heater and Thermistor Cartridge Plugs
Disconnect all heater cartridge plugs and the thermistor cartridge plug from the PCB.
Step 4: Disconnect the Part Cooling Fan
Unscrew the part cooling fan duct (2.5mm Hex) and remove the part cooling fan plug connected to the PCB.
Step 5: Remove the Old Hotend
Using a screwdriver, remove the two
...
socket head screws on the heat block (2mm Hex). Once the screws are loosened, the
...
Hotend should be able to wiggle free from the printhead.
Step 6: Install the New Hotend
Ensure that your new Hotend has the four heat break tubes installed, as well as the
...
socket head screws. Apply a small amount of Loctite 243 on the socket head screws and insert them into the printhead.
...
Gradually torque the screws to a value of 0.9 Nm going back and forth between the two screws to apply even pressure.

Note: When installing the Hotend assembly, ensure that the larger chamfer faces the part cooling fan and the wires are routed around the back/bottom of the printhead. |
Step 7: Reattach the Part Cooling Fan
Install the part cooling fan (2.5mm Hex) hand tight and reconnect the fan cable.
Step 8: Reconnect the Thermistor and Heater Cartridge Plugs
Insert the thermistor plug and the heater cartridge plugs into their respective connections on the PCB.
Step 9: Secure Hotend Cables
If your part cooling fan duct has a cable tie point, use a zip tie to secure the Hotend cables in place.
