Machine: 130W custom build
Problem: Only cuts 60 degrees of a circle.
I’ve just got my machine built and I’m doing the first tests. First off I did a square with no problems, but when I try to do a circle it just does the first 60 degree arc and quits - always the exact same portion of the circle, even different circles of different diameters in different positions in the workspace. LightBurn reports that it’s busy (at 20%) and I can’t get anything to work after that besides restarting LightBurn and the LaserBoard. I’m just doing a line cut at 20mm/sec and 100% power, (I have my current limited to 6mA). The gcode looks fine to me - obviously the square is just four G1 lines where as the circle is many more. So it would seem that the Smoothie buffer is getting full and hanging up. I’m thinking that there’s a setting in LightBurn or the config.txt file that I need to tweak, but I’m not finding anything yet. Any ideas of what I should do?
