As long as I can associate the job with a particular gcode file, I can know the settings I used. That tells me that “image thing” is engraved at 1200 mm/min, 85% power, and 339 DPI with jarvis dither and a 1-pass profile cut at 120 mm/min and 100% power. When I create a gcode file, however, I try to embed the major settings in the filename i.e. And, at some point down the road, I’ll guarantee I’ll go back into the LB file and jack with some settings… and all is forever lost. And, of course, I’d never think of scratching the settings on the back of the piece. The direct control thing is really neat, BUT… after a run I have no way of telling what settings were actually used for that burn. I particularly like method of testing with direct control and then commit the gcode to SD. LightBurn can do direct machine control without generating a gcode file… or you can create a gcode file to use with another sender and/or SD card. And the LB forum, like this one, is generally well-behaved and helpful… and Oz (the LB owner) and other LB staff actively participate to provide in-depth help and address issues. They also advertise installation on TWO computers but will happily extend that to THREE machines - again, when asked nicely. The 30-day trial is pretty generous… but if something comes up – and you ask nicely – they’ll generally extend it a bit to help you get your machine going. I’ve also found the Lightburn staff (it’s a very small outfit) to be very friendly and helpful. Pretty neat! I’ve also discovered since that my Chromebooks with Lightburn can do this also… it’s just a serial/USB connection. We also have two friends who sprang for Neje Master 2S Plus laser engravers for Christmas this past year – on our recommendation and promises of help to get them going – and we set them up with trial Lightburn on Windows laptops and got direct LB-control of their machines. I’ve got Lightburn running on two Chromebooks and a Linux Mint laptop. I then use V1Pi/CNC.js on Pi-3B’s to send the cutfiles to any of my several machines. I’ve got both diode and CO2 lasers and can generate cutfiles – both gcode and DSP – with it. ![]() I’m a Lightburn fan (and not affiliated in any way)… and it’s worth every penny IMO.
