If I try to send an 8cmx12cm , 900dpi image to my G2, Lightburn hangs on the “building job” stage, the task manager shows over 4GB of memory being used, and eventually I get the “Lightburn Crashed” dialog.
Nothing is written to the log file even though I’ve turned on debug logging. Would anyone have an idea whats wrong? Smaller images work okay but do take sometime to build in lightburn.
I’m using 1.7.06 and have tried uninstalling and reinstalling but still get the same issue.
As far as I know, this is a grbl or gcode machine…?
Suggest you turn this off, until support requests it… I believe the file is in the documents folder.
I’ve got a few lasers and I don’t remember seeing this message… ?
Lightburn is pretty efficient, so I wonder if something else is going on. I ran it for years on an old 4 core processor with no issues. Only time I remember thinking it’s a bit slow was when it was computing the 256 passes for 3dslice.
If you have this set to grayscale it has to change the power constantly, so sending power commands constantly. This generates lots of gcode… The higher the resolution the more data it generates.
Have you tried using a dither?
If you don’t mind, you can post it and we all will look at it on our machines.
Make friends with the preview tool… does it work there?
No, the G2 is BSL not GRBL
Does not the same idea apply to any machine… at least the grayscale generating a large amount of data?
Thanks for your replies.
I found the issue. I was sending an Atkinson render, but wanted 100 passes for a deep engraving, so set that in the layer dialog. The software it seems was attempting to send the file 100 times, which caused Lightburn to max out my cpu/memory and eventually crash.
I worked around it by setting the layer # of passes to 1, and instead setting the job to repeat 100 times in the framing dialog. I’m not sure why Lightburn works this way tbh, but I guess there’s a reason for it.
LOL, good one.
That would do it.
