I can confirm that on mine, the laser stays on and the fan spins up. I would suggest manually downloading the latest firmware here: Snapmaker 2.0 Firmware Updates and Downloads and putting it on the USB drive. Then select the USB drive and update file from the file select menu to ensure the snapmaker, and the 10W module is fully up to date. If that doesn’t fix it, double check your cables to make sure they’re fully seated and in the correct direction (the 10W actually reverses direction vs the 1.6W module). Finally, contact support, as this might be a hardware issue with the module itself.
