Not yet. You are the only person who’s ever brought this up, so it’s not as high priority as a number of other things in progress right now. It’s logged, and will get addressed - I have a link to this thread (or the other one) in the bug database so I can notify you when it’s fixed.
Just curious is your piece of wood that your are engraving perfectly cylindrical or is there any variance at all in the diameter ? Rotary device …chuck or cylindrical does not matter if the cylinder, engraving surface is not a constant .
Well it’s a 3/4’ dowel from the hardware store. It’s not going to have aerospace tolerances. Here is the thing. The issue also comes up when we are engraving borosilicate and quartz crystal tubing, which are dimensionally very consistent. The gap were seeing shows up in the G-code Lightburn generates. We do not have this issue with code generated from Laserweb, but that has other limitations. It’s a bug in Lightburn, unfortunately for us it’s a low priority.
Thanks Oz, Looking forward to it. Just as curious. Do you think there is any benefit from running a Ruida/DSP style control. As I understand it those do not generate Gcode files and maybe the processing of the image to raster is different?
I can’t say for certain, as I’m not sure if the issue is in the image sizing, or something in the gcode. I do track precision errors in gcode from rounding, and add them back in as they accumulate, but I need to run some tests to figure out if this is image specific or also vectors, just an issue with rotary, etc.
