I am seeing an issue where the same project file that works in 1.7.06 results in a file that mostly just goes through the motions with the laser off in RC02 and RC03. I am using a GRBL profile in LB2.0 because the air assist in the snapmaker profile is broken in all three versions of LB.
I’ve tried this with LB project files generated by me, and by others, so I don’t think it’s an issue with the file. Some of the shapes are burning properly, and others not at all. If I re-run the job, the same shapes get skipped.
Place several simple shapes, ‘Line’ mode, 50% power, save the project, and use ‘Save GCode’ to save the output file.
Open the same project in RC 3 version, use ‘Save GCode’.
Look for differences that might explain the behaviour, or attach the two gcode files to an email to support@lightburnsoftware.com along with the project file, your support data (Help > Generate Support Data ), and a link to this topic, and we’ll take a look.
