I’m new to Lightburn, I just recently learned about it and now I’m testing it out on my laser. When I learned that Lightburn was powerful, affordable and natively supported Marlin, I was sold! My machine is a custom built, i3 clone, 3D printer, running Marlin on a GT2560 mainboard. My host machine is running Linux Mint 19.2.
The problem I’m having is that I can’t get Lightburn to connect to the printer unless I run it as root. I’ve confirmed that my user is in the correct groups (tty, dialout) and that my user can connect to the printer with other software like Pronterface, but unless I run Lightburn as root, the debug log show that the port could not be opened, suggesting a permissions issue.
Running as root everything seems to run fine and I was able to do a test engraving in very short order, I’m loving the software so far and looking forward to using it some more!
I came across a fairly important bug while I was testing, but I’m not sure of the exact place to report it, should I post bug details here, or is there a better place?
