Laser malfunctioning

what is cutting is entirely different from what I sent to the machine

Sometimes this is a licensing issue with a “cracked” LightBurn file obtained from somewhere other than the Official Site.

Some previous discussions show various “entirely different” results:

Laser burns Zigzag curves

Hi! I’m quite new to this topic. Just bought a hobby / china laser called Vevor L1717. It was recognized in Lightburn as a GRBL device, I have adjusted my axes and e.g. burning a 20mmx20mm square results correct measures. However, whenever there is a curve in the object it does zigzag and rubbish, see the attached pics. Looks like a wrong setting to me. (With the shipped iOS app, it burns correct shapes). Any Idea how to fix this? [photo1683552953] [photo1683552953 (1)] My config values ($$)…

Creality Falcon 10w strange draw

Hi dears, i tried Lightburn with a new Creality Falcon 10w. I added the laser using the configuration file provided with the device. However the cut looks like nothing and looks like the laser draw random things [image2] [image1] I did try some eagle cut that was provided with the machine on LaserGrBL and it was perfect [image0] Did you have an idea what could be wrong ? (first laser machine and total noob here) thanks a lot

Gcode image is diferent in lightburn

Hi , When I make a drawing in Lightburn and save it in Gcode the drawing looks different. how to solve this? [p1] [p2]

If that’s not the problem, some pictures and perhaps the lbrn2 file will give us more to work with.
