New Linux Mint Install LightBurn not Connecting to Laser

LightBurn Software Questions OS Specific
1

I may have created a problem for myself. I got a new computer – installed the latest Linux Mint. Then I copied the Lightburn install from my old machine over to the new. This required that I handle the licensing stuff – but I was able to get that done.

I am able to successfully run Lightburn – but I cannot get it to talk to either of my two lasers (i.e. an xTool D1 non-pro, and a JPT Galvo.) I made sure to ensure that I had added my user to the dialout group as instructed in the LightBurn Installation documents and I have also validated that my system is seeing the laser on the USB port. I am out of ideas on what to try.

For reference the output from the dmesg is below:
[18673.479606] scsi host4: usb-storage 1-8:1.0

Anyone have some ideas on what I can try next?

I thought I replied to this… but I’m guess I’m hallucinating or someone else on another thread is wondering about me… :face_with_spiral_eyes:

Had a similar issue with the fiber… I assume this is an EZCad2 board?

Looked a lot like yours… I skipped a step in there somewhere… but follow this thread and I think it’ll get you connected…

If you have issues, sing out…

Good luck

This looks like it may have fixed things. It is finding my galvo laser and I am able to frame a project.

I’ll spend some time tomorrow and see if things are working correctly for all of my lenses and also with the xTool D1 non-Pro. I am anxious to start using my new more powerful machine to do my laser projects.

Thanks so much Jack – I’ll report back on my results tomorrow night.

If this resolves the connection issue. Mark the pertaining thread as a solution…

If you have other problems… start a new thread… Users can’t find information buried in a post where the title isn’t related…

Take care, have fun

Thanks again Jack.

I did find out the problem with getting Lightburn to communicate with my xTool D1 non-Pro in my fresh Linux Mint install. Apparently ch341 UART converter was being claimed by the BRLTTY application. This is something that is automatically installed when you do a default install of Linux Mint. The only way I could find to get this cleared up was to remove the BRLTTY app (not a big deal for me since I don’t have a braille keyboard.) The command for doing so within Mint was

sudo apt-get remove --autoremove brltty

I hope this helps someone else in the future.

I thought that was in the link I sent you… it’s a known issue with that driver…

Glad you’re up…

Take care
