There are a few reasons you may need to change the extruder head on and Adventurer 5m Pro. The process is pretty straightforward, and should take 5-10 minutes. Follow the steps below to ensure you completed the change successfully.

Step 1:

Ensure the printer is turned OFF

Step 2:

Begin by cutting the filament just above the extruder head, similar to how you would change the filament.

Step 3:

Identify the red levers on the print head, and squeeze them inwards together. This will release the print head, which should drop out, or you may need to gently pull down on it.

Step 4:

Prepare your new nozzle and ensure you orient it so the connector is towards the back of the printer. Then clip the nozzle up into the print head, ensuring you hear a 'click' and see the red levers move.

Step 5:

Turn the printer back ON and use the preheat function to check that the print head has been installed correctly.

Step 6:

On the printer's LCD screen go to "Settings" and change the nozzle size to the new nozzle you just installed.

Step 7:

In the "FlashPrint" software, change the nozzle size to the new nozzle you just installed:

Note: If you want to take the extruder head apart (you shouldn't need to do this, but filament may get caught on the cog/gear!) there is a step-by-step video here
