Has anyone had the issue that when cutting an object that is just lines that it goes over them twice? is this because it sees the like as an object and it tries to cut both sides?
More or less. You need to make the lines 0.025 thick. At least on Corellaser
Yes. Either the line is thick (I use .001mm for the stroke weight on any cut line) or the software actually draws it as a box (a really really skinny box). I’ve had the box as a line issue with LaserCut on a big Chinese laser - only saw it under seriously large magnification.
