- The front fan cools the print cores, the side fans cool the print bed.
- The "jaw" swings open, and holds the front fan.
- The AA printcore is meant for PLA.
- Front fan no longer spinning, temperature not regulated
- Prints failing due to no extrusion
Wire for front fan was snipped due to a incorrect wire run during the last head rebuild (black and white cable that runs on the left inside of the jaw)
The fan was replaced.
- The bowden tubes were disconnected from the head
- The cable was disconnected from the head by unscrewing the rear two long screws on top of the head and opening the hatch.
- The head was removed from the 3D printer by snapping off the two axles from the sliders
- The four screws on top of the side fans were removed to reveal the fan and sensor cable connectors on the rear of the head
- The jaw was removed from the head by squeezing the hinge
- The screws connecting the metal jaw to the plastic front fan older were removed
- The metal cable holder was opened to free the black and white cable
- The fan was replaced
- The wires was run through the metal wire holder on the side of the metal jaw (re-closed) and run through the same path as the capacitive sensor cable (red and white) to be plugged into the cable connectors.
- Follow the steps in reverse from step 6 to replace the head.
The left AA printcore was replaced.
- These steps are well-documented by Ultimaker.
A test print (benchy) was successful.
