laser head fan not spinning but the one beside psb is working fine

According to this post ( I tried reconnect FFC several times. All failed to make the fan spin. Any other suggestion to fix this problem?

Attach some closer look of the FFC connection. Thank you.


  • Please check the FFC is correctly inserted into the Emblaser main PCB.

    Changing the orientation at one end will not work if the other end is incorrectly inserted.

    The silver contacts should be facing towards the centre of the PCB.

    Always release the locking mechanism before trying to adjust the FFC. Lift the locking mechanism, make sure the FFC is fully inserted and then push the locking mechanism down.

  • Thanks for the instant response! Issue was caused by the other side.
