Installing the Extrusion Upgrade kit
Loosening the electronics
Disconnecting the cables
Important:
While removing the cables, do not pull on the wires.
Always pull on the plugs.
• Take the main board carefully. Ensure that the wires are still
connected when you hold the main board.
• Remove the wires from the green terminal HEATER 1 by
pressing the top of the terminal with the flat screwdriver.
Note:
When placing the machine upright, take care of where your
main board is, so you do not break it.
Note:
If you have an older model of the main board on your
Ultimaker, you need to loosen the screws instead of pressing to
remove the wires.
• Disconnect the hot end fan from the middle of the board.
• Disconnect the feeder motor from E1 on the main board.
• There’s a ferrite core around the motor cables. Open it so you
can remove the feeder motor wire completely. (It’s possible that
your Ultimaker is older and doesn’t have the ferrite core).
• Disconnect the PT100 sensor from TEMP1 on the main board.
• Disconnect the print head fans from FAN PWM on the
main board.
• Pull the braided sleeve with cables and the feeder motor wire
out through the hole in the bottom left corner and the hole in the
back plate.
• Place the Ultimaker back upright and move the build plate down
for easier access during the next steps.
• Remove the two screws (M3 x 12 mm) and locknuts from the
electronics cover and set them aside. Use a socket wrench or pliers
to hold the locknut, while unscrewing the screws from the inside.
• Remove the cover and place it aside.
• Unscrew the four screws (M3 x 25 mm) from the main board and set
the screws and spacers aside.
