Final Assembly

Motherboard Assembly

  1. Plug the peel-motor-asm into the 2-pin connector on the PCB

  2. Slide the peel-motor-asm into its corresponding cavity in feeder-frame-8mm

    • Tuck the excess cable into the empty region behind the peel-motor-asm

  3. Tilt the PCB slightly to insert the drive-motor cable into the six-pin connector on feeder-motherboard

  4. Press the PCB flat into feeder-frame-8mm

    • Make sure the cable is not caught between them - it should lay flush

  5. Press drive-motor into its cavity while ensuring it is flush with the back of feeder-frame-8mm and the cables are well routed, as shown

  6. Insert 4x M3x12mm flathead screws into the holes in the PCB as shown below

    • Use automatic screwdriver with power set to 6

QC Check - Test if the buttons on feeder-frame-8mm can easily actuate the switches on the PCB before proceeding

  1. Install a drive-motor-bracket

  2. Insert 2x M3x12mm flathead screws

    • Turn the screws in equal amounts before tightening them both to the final torque spec
    • Tighten the 2x M3x12mm flathead screws to 55 cN.m (5.5 N.m) with a 2mm hex head driver


    Over-tightening can lead to bracket damage and motor skewing in the feeder-frame-8mm

  3. Check that the drive-motor is still flush and hasn't skewed because of tightening

    • If it appears crooked or not flush, loosen the screws and readjust the drive-motor

  4. Use a blade to clean up any loose plastic that was pushed through the drive-motor-bracket mounting screw holes during installation

Failure to perform this step may cause issues with cosmetic sticker installation later on

Install the release-lever

Wearing safety glasses is required while installing springs

  1. Install the spring

    • Grab a spring and a release-lever, and hold the spring in the release-lever as shown
    • Match the other end of the spring up with the circular cutout in the feeder-frame-8mm print
    • Finally, drop the release-lever into the feeder-frame-8mm

  2. Insert an M3x15mm flathead screw from the backside and drive it in using the automatic screwdriver on the 4 setting (0.25 N*m).

    • Make sure the arm can still swivel easily
    • Make sure that the arm does not have any lateral movement

Install the peel-gear-box

  1. Obtain peel-gear-box

  2. Place peel-gear-box in place, engaging with the worm-gear in peel-motor-asm

  3. Insert 2x M3x12mm flathead screws into the locations shown using automatic screwdriver set to 6

Install the drive-wheel-asm

Note on drive-motor shaft angle

Drive-motor units may come from factory with a shaft rotated at an angle that's not ideal for set-screw tightening. If this applies to the feeder you are handling, follow the steps below:

  • Power up to the affected units by plugging it into Gundam
  • Press the feeder's jog-forward button until the shaft is at an optimal angle for subsequent assembly work

  1. Place the 2 Drive Wheel Shims in the drive-wheel-asm cavity as shown, with the drive-motor shaft sticking through it

  2. Drop the drive-wheel-asm onto the drive-motor shaft

  3. With one hand, press down firmly on drive-wheel-asm while using your free hand to tighten the shaft-collar-asm set-screw

    • Tighten the M2.5x3mm-set-screw to 30 cN.m (0.3 N.m) with a 1.27mm or 1.3mm hex head driver

  4. Remove the Drive Wheel Shim

Install drive-motor-cover

  1. Place a drive-motor-cover over the drive-wheel-asm

    • The drive-motor-cover should lay flat with none of the cables preventing it from being flush against feeder-frame-8mm

  2. Insert 3x M3x12mm flathead screws in the locations shown below

    • Use automatic screwdriver set to 6

You may now proceed to OQC
