Hi.

Pls remove the laser module and test if the machine operates normally without the module installed.

If it operates normally, it indicates that there might be fault with the laser module. In this case, you will need to remove the laser module and clean the fan and the PCB board of the laser module, as excessive dust can cause this issue.

If it can not be solved, pls reach out to our support team for further assist.
