Please upload the current version of config.h for your FluidNC firmware, a small LightBurn project that demonstrates this behavior (the smaller the better), and the GCode generated by LightBurn for the small project (click File - click Save GCode).
The files should upload by using drag and drop (into the reply box) or with the Upload button (up arrow - rectangle box icon) in the middle of the top of the reply editor. If the permissions interfere, please change the file extension to .txt and retry.
Spindle drivers and carving programs may come to a full stop after traversing to begin a plunge operation. If you imported GCode from another generator it may have saved z moves which could appear as full stops as your controller counts them out.
Ofcourse I tried using the standard config file for FluidNC but in that I need some additional configurations related to homing and laser functionality.
So I discussed with FluidNC developers in discord and got them sorted from fluidNC side aswel.
here you can find the standard configs.
Among the list, I took [3axis_v4.yaml] file as reference and modified it to the below. Laserx.txt (2.0 KB)
Just a note config files are always .yaml so you gona use my config, please rename the extension to .yaml instead of .txt
