Important Safety Information: Disconnect your Gigabot from power and make sure it is turned off during the removal and installation processes!
Important Product Information: Inspect the top of your existing motor to determine if the motor was made by Motech or by LDO. Inspect your replacement motor to determine if it was made by Motech or LDO. If your motor was made by Motech and you are replacing it with a Motech motor, then you can continue on to the instructions below. If your motor was made by LDO and you are replacing it with an LDO motor, then you can continue on to the instructions below. If your motor was made by Motech but you are replacing it with an LDO motor, then you will need to follow these instructions to rewire the motor cable connector: Link to article on wiring a Gigabot for LDO motors
After June 8th, 2022, customers who order replacement motors and have a Gigabot made before June 8th, 2022 will receive a new motor cable as well. This motor cable is necessary to use because it has a JST SMR-04V-B housing on it to mate with the compatible JST connector on our new motors. It has different colored wires, so you will need to wire it into the Azteeg control board with the order, from left to right, Blue Stripe -- Blue -- Yellow -- Yellow Stripe:
1. Unplug the motor cable and the limit switch, then remove the outer screws securing the motor to the frame as indicated in the photo below. Keep your hands on the motor during this step to prevent the motor from falling.
2. Remove the belt from around the pulley on the old motor.
3. Holding the motor in one hand, route the Y-belt into the pulley, ensuring the belt is straight and not twisted in any way.
4. Using two M5X45 screws and two M5 washers, secure the motor to the side of your Gigabot’s frame (placement outlined in photo above), using caution to not over-tighten.
5. Rewire the motor cable if needed as described at the beginning of the article (Link to article on wiring a Gigabot for LDO motors) then plug in the motor cable and the limit switch. The order of the limit switch wires does not matter.
6. Re-tension the Y-axis belt using the instructions in this article: Belt and Wheel Tension
The video below outlines installing the new motor, starting at 1:32 (the video below will take you to that exact timestamp).
