Information: 

This guide outlines the steps to replace the USB adapter board on a Creality K1 3D Printer. Ensure the machine is powered off and unplugged before beginning. An allen key / hex wrench is needed to undo the screws in harder to reach parts internally, so make sure you have one. Normally these machines have some included in their toolkit.

Procedure:

  1. Prepare for Repair:
    Power off ther machine using the rear switch and disconnect the power cord. Carefully rotate the printer to the right side to access the bottom panel. Make sure there are no objects it will rest on potentially cracking the acrylic panel.

  2. Unscrew 6 Screws from Bottom Panel:
    Loosen and remove the six hex screws securing the bottom panel in place. Keep these screws in a safe place for reassembly.

  3. Remove Bottom Panel:
    Gently lift off the bottom panel of the printer to expose the internal components. Locate the cable connecting the bottom panel fan to the mainboard. Unplug this cable carefully from its connector on the mainboard.

  4. Unscrew 2x Screws from Adapter Board:
    As these are partially blocked by the frame, an allen key / hex wrench is needed to undo the screws. Normally these machines have some included in their toolkit.

  5. Remove Cable from Adapter Board:
    Disconnect the cable connected to the USB adapter board.

  6. Replace Adapter Board:

    Reconnect the cable to the new USB adapter board and secure in place using the two hex screws removed in step 4. Remember to screw in the grounding cable (colored green and yellow) under the lower screw so the circuit is grounded to the frame.

  7. Reconnect Fan Cable:
    Plug the bottom panel fan cable back into its connector on the mainboard.

  8. Secure 6 Screws for Bottom Panel:
    Secure the bottom panel in place with the screws from the start.

  9. Test Machine:
    Once everything is reassembled move the machine back onto it's feet. Plug in and power on to test that the USB connection is functioning correctly. Insert a USB drive into the port and a message should appear indicating the system has recognised the USB. Try copying or printing directly from the USB to ensure it is correctly communicating with the mainboard.
