Thanks for the feedback and direction everybody. I’m downloading the 20.3 version, that’s the last one they have to offer before they moved up to 21. Linux Mint 20.3 "Una" - Linux Mint
The one thing that has some degree of concern. I’m just about done with the trial period so I have to pull the trigger on purchasing it. They give you up to two systems you can use it on, via. to be officially licenced. They obviously are going to count each partition/installation as one separate computer but I want to have at least dual partitions on the windows laptop, with the windows OS still using Lightburn as a back up or if there are some weird bugs with software/hardware compatibility in the future and to include upgrading my laser, and it’s second partition running Mint, again it’s own going to get a copy of Lightburn on, and the additional computer, my main one, it too being technically a third installation. I hope I don’t have to choose only two and stay limited to only two on the same purchase.
I’m digging into mastering Lightburn as a secondary, or that final filter/software/driver for the laser cutter, knowing full well that I need control in this environment regardless of the models/designs being created with other software, cad, or in this case, I’ll be digging into Fusion 360 next.
When you change out a motherboard, Lightburn seems to detect it as a new computer…
I suspect it will run on both partitions, if it’s looking at hardware…
Lightburn is also very good about issuing you a 3rd seat if you need it…
I’ve been in hard/software since the 70’s. Lightburn has got to be the best product I’ve ever used. Support is fantastic, on top of that they are nice people.
If you pass on Lightburn, it’ll be a huge mistake.
Thanks, that’s good go know. My daily driver has 700 gigs of data to back up, so creating a separate partition and dual boot may be the route to go so I can keep the original OS in tact without having to buy another hard drive just to back up files on, for I would rather back them up to the new partition after it’s proven stable. It’s a frankenbox so wasn’t exactly easy to get the original OS dialed in when I moved away from windows in 2019. It would be also a neat thing for all 32 gigs of ram to be recognized rather then limited to it’s only seeing 16 and nothing in bios was able to change that.
I’m not passing on LightBurn, it’s still going to be kept and used, but working in 3d is better especially with the models I’m focused upon for the laser cutter which are remote control aircraft.
Regarding testing LightBurn on several comuters / partitions at the same time, an easy way to do it is, as you also write yourself, to have a comuter as “master” which is not touched, I use my macbook for that, it is my “construction and design” computer. In the workshop I have two old PCs with LightBurn installed. When I’ve tried the different variations of Linux, it was easy to start up LigtBurn and “unregister” the program from within LightBurn itself, and use it on the next Linux version. I did until I landed on Ubuntu 20.04
I wish you success with that.
Word: if you have only one copy of any data, tomorrow you will have none.
Backing them up on a different partition means when that drive dies, it takes both copies down.
Newegg sells 4 TB spinning-rust USB 3.0 external drives for a hundred bucks, so if your data is worth having, give up your favorite vice for a week and make a real backup before messing with partitions.
Source: been there, broke that, kept all the pieces.
Make some progress. I ended installing 20.3 Mint along side the old one and that at least got Lightburn working. It will not recognize my laser so have more rabbit trails to follow to attempt to get that element going. Seeing it’s a common thing with Linux not being able to recognize laser cutters so I may end up forced to still use the windows laptop just for the cutting part and do the design work on my main system, now upgraded.
QinHeng Elecronics HL-340 USB-Serial adapter is what appears to be the laser, unplugging the usb from it, it goes missing so at least have it somewhat pinpointed, so it’s not ghosted or something.

This is what it’s been doing from the beginning, and I have tried all three versions of GRBL. I even have a windows version of LB running in Wine, it’s still the same issue.
There is only the USB going from the laser cutter, another for the wifi stick, another for a mouse and another for the keyboard. Nothing else is connected.
