Hi I installed linux mint and lightburn but lightburn can’t see any usb ports I made a mistake at the beggining and didnt replace $USER but then I tried again with my username and it displayed info that it’s already done so I have problem with connecting the laser.Can anyone help?
This is not a LightBurn problem, this is a Linux + CH340 driver issue. Here is a guide also for Linux how to get the laser recognized (usually it’s a specific package that blocks the USB port. Setting up the software - Diode Laser Wiki There is also a video linked where I showed the procedure for Ubuntu. Should be similar.
That worked and it detected the laser but the laser is very weak
That’s a settings issue then 
What settings did you use?
