The instructions for replacing the head cable on your Gigabot 2, Gigabot 3, 3+, or Terabot are outlined below.
Jump to GB2 head cable replacement
GB3, GB3+, and Terabot Instructions:
Tools Needed:
- Large flat head screwdriver
- 2.5mm Allen key
- Small flat head screwdriver
Parts Needed:
*Important Safety Information: Disconnect your Gigabot from power and make sure it is turned off during the removal and installation processes.
Instructions:
We strongly recommend testing the new head cable before performing a full installation to ensure that it provides the desired solution. Leave the old cable in place, except for terminals and connectors, until you have verified that errors are no longer present. In this initial testing phase, please refrain from installing the new cable into the Panduit and wire covers. Instead, connect the wires into the Azteeg and the connectors on the back of the print head as described in the upcoming steps. Route the cable along the filament tubes and temporarily secure it with tape or zip ties as shown in the photo below.
- Unscrew the heater and fan terminals on the Azteeg control board shown below according to the board you have, and remove the wires.
Azteeg X3 PRO
Azteeg X3 V2:
-
Heaters are on the bottom left corner of the board, and the fans are on the shield on the middle left.
1. Remove the back cover of the print head using a 2.5mm Allen wrench, then unplug the wires shown below. Please note that the connectors have locking mechanisms that need to be pressed to release.
2. Plug the new head cable wires into the respective positions, making sure that the pair of wires labelled "OR" (for "Outrigger") are connected together. (Shown below, it connects to the yellow and orange wire in the print head.) Slide the connectors back into their slots in the back of the print head and reinstall the cover.
3. Insert the head cable into the same terminals on the Azteeg as shown below. Please note that the wires might be different colors than before, so make sure the correct colors are in the right places.
Azteeg X3 PRO:
-
The order from left to right is as follows: red, gray, blue, white, green, brown, pink, yellow.
Azteeg X3 V2:
-
Heaters are on the bottom left corner of the board, and the fans are on the shield on the middle left.
4. Once it is confirmed that the printer no longer resets or fails to heat or run the fans, proceed with removing the old cable.
5. Remove the Panduit covers and the grommet around the wires, and pull the cable out of the electrical box.
6. Continue to remove the Panduit covers on the bottom and side of the frame of the machine and remove the old head cable wire.
7. When you get to the cable carrier, unscrew it from the frame and brackets, and open the clasps that hold the wires inside.
8. Continue removing the Panduit all the way until you reach the print head.
9. Route the new wire in the cable carrier with the wire separators (if you have them) back to the electrical box. A video on how to organize the wires with the wire separators is located here.
10. Replace the covers on the Panduit as you go to help the wires stay in place.
11. Once back outside the electrical box, put the wire through the grommet cap (or flex cable gland, if you have one), insert it into the hole of the box, and pull it through. It might be longer than needed, so in the Panduit on the bottom of the frame, you will need to double back the length that you don't need. Ensure that all connectors have ample strain relief.
12. Close the electrical box and continue printing.

- red and black cartridge heater wires from the left side
- white and blue thermistor wires from the bottom
- brown and green fan wires from the left side
Remove head cable from the electrical box
Remove cable grommet from head junction box and replace with new flexible strain relief cable gland (if not done already.)
Assemble new cable in the opposite order
- Note when wrapping spiral wrap start at the print head and wrap towards the electrical box.
