Hi
premise that I own two notebooks and an Ortur Laser Master 2 Pro S2 that I have been using for almost two years with LaserGRBL. Seeing the functionality of Lightburn I wanted to test it on the new notebook and was fully satisfied.
I wanted to install Lightburn as a trial version on the old notebook (with Windows 11 upgraded from 10) where I had installed and used the Ortur Laser Master 2 Pro S2 with LaserGRBL. The test file
I had used before (a circle and a hexagon in red to engrave, a test script in green as a fill and the black square to cut) came out totally wrong
on the old notebook.
I tried to see if the problem was due to the old drivers (STM Micro v1.5 64Bit, CH340, …) so I uninstalled LaserGRBL and LightBurn. Once I restarted the old notebook and reinstalled Lightburn, the test file was engraved wrong again. If I try to move the laser head horizontally with 10mm pitch from Lightburn it also moves in y (if I press right arrow x=10; y=0 the first time, if I press right arrow x=21; y=1 the second time, if I press right arrow x=32; y=2 the third time, …) and vice versa.
If I use Lightburn on test on the new notebook, I have no problem either in moving the laser head or engraving any design.
I have not found similar problems on the forum.
Why does Lightburn work badly on the old notebook? Please note, LaserGRBL works correctly on both pcs.
