Hi, I am having a problem with engraving grayscale content…
I am getting a hough line shift or step loosing. This only happens with grayscale, 100% works fine as shown in the image…
Any idea? Thank you!
It seems to be Lightburn related, I checked the timing belts and the cutting and black engraving works just great, just grayscale seems to cause this extreme line shifting or step loosing on the x-axis…
What speeds do you use for “grayscale” and ordinary fill?
That’s what I was thinking, too…
I tried all kind of speeds, even lowering the acceleration with $120=150 and $121=150.
No change at all but 100% is always accurate, just with grayscale images, the step dropping is huge…
Very strange…
With the same settings for a pure black image and a greyscale image…
Not to put too fine an edge on it, but exactly what speeds are you using?
Copy and past the contents of the Console output for the $$ GRBL command so everybody can see what’s going on.
It would be helpful to see the *.lbrn2 files for those testcases: please upload them, too.
Thank you, this is the file from my latest test…
And the GRBL $$ configuration too, please.
Sorry, I am not home for the moment and will be back next week… I only have my Mac here, not the laser… Will post it asap!
Thank you!
