The best case scenario is that you can adjust the settings you need in a nice user interface, without learning manual configuration via a G-code sender. And if you’re building your own laser or CNC, you’ll need to know all about controller settings.

Even if you’ve bought a pre-made laser or CNC machine, you’re still likely to benefit from fine-tuning the settings for your materials or needs. The touchscreen will put the machine into G90 mode, which will ruin the gcode file being executed.The brains of laser cutters and CNC machines, G-code controllers, include settings covering speed, physical limits, directions and intensity (of a laser beam, or rotational speed of a spinning endmill). There are a couple run boundary functions in Lightburn I’ve gotten to work over USB, but I rarely use them.Īnother fun quirk - if for any reason the laser print pauses (ie, you open the enclosure) the job will permanently fail. But that doesn’t work with G91 moves and you get the wrong boundary. So you simply look through all the gcode, find the min and max, and that’s your boundary. I suspect the reason this happens is the touchscreen assumes G90 mode, and the boundary for moves in G90 is the single largest and smallest X and Y coordinate. You’ll just have to double check you’ve sized everything correctly and have faith. Run boundary will always fail because Lightburn generates relative moves in G91 mode, which is incorrectly calculated by run boundary in the touchscreen. I was having issues with Lightburn generating S parameters instead of P parameters for M3, which is a snapmaker specific quirk that is dealt with in the Snapmaker specific Lightburn device.
