When using bw image, bmp,png,jpeg. We setup image on C0 12000/50/1pass, stucki, dither or greyscale, in 35w or 70w mode, frame, focus, start job. Job runs 1-4 minutes, then laser freezes and stops lasing. Console say stream done, complains about bad g code. Funny thing i saved g code, closed lightburn, opened g code file with lasergrbl, framed, focused, set speed, set power same as before. Then ran it. Job completed perfectly first time. Why does lightburn not correctly run the jobs it creates? I also loaded lightburn with the previous g code and it failed same way. What am i missing?
