Change WASP SPITFIRE Extruder

Here’s a step-by-step procedure on how to change the Wasp Spitfire extruder on your 3D printer:

STEP 1: TURN OFF THE PRINTER

  • Before starting any operation, make sure your 3D printer is turned off and disconnected from the power supply to ensure safety during the process.

STEP 2: UNPLUG THE RJ45 CONNECTOR

  • At the top of the extruder, locate the RJ45 connector and unplug it. This connector is used for electrical communication with the extruder.

STEP 3: REMOVE THE NYLON BOWDEN

  • At the top of the extruder, you will find a quick coupling for the nylon tube with a loop. Press down on the quick coupling ring and simultaneously pull up on the nylon tube.

STEP 4: UNSCREW THE SCREWS AND REMOVE THE EXTRUDER

  • Underneath the aluminum plate that supports the extruder, you’ll find two fixing screws. Using a 2.5mm Allen key, unscrew these two screws. Once removed, you can pull up to completely remove the extruder from the printer.

STEP 5: INSERT THE NEW EXTRUDER

  • Take the new extruder you want to install and place it in the same location from which you just removed the previous extruder.

STEP 6: TIGHTEN THE SCREWS

  • Under the aluminum plate, screw the two screws back in to securely secure the new extruder in place. Be sure to tighten the screws properly, but avoid applying excessive force so as not to damage the new extruder.

STEP 7: INSERT THE NYLON BOWDEN

  • Reconnect the 6 mm diameter nylon tubing into the extruder quick coupling. Make sure it’s securely inserted and locked in place.

STEP 8: RECONNECT THE RJ45 CONNECTOR

  • Reconnect the RJ45 connector that you disconnected earlier, making sure to pass it over the rubber bands.

STEP 9: TURN ON THE PRINTER AND CALIBRATE THE PRINT BED

  • Turn on the printer and proceed to calibrate the print bed. This will ensure that the new extruder setup is properly leveled and that printing can be done accurately.
