My question, I am engraving on scratch paper therefore I have an inverted image. The issue I have is that the machine engraves the image twice, and as you can imagine the second time it passes over it, it begins to cut the paper.
I have only one pass selected on the job, I have no other idea
You likely have 2 lines in the design itself. Either you have overlapping lines for some reason, possibly a duplicate object, or what you think is a single line is actually a stripe with 2 sides, with each side cutting along the line. Zooming in would reveal this.
Also step through the Preview. It should follow the actual planned path and reveal whether or not you’ll be going over the same spot twice. Good indicator to review what’s going on there.
How was this design created? This often happens with traced images where people are expecting a line to be a single line rather than an area in LightBurn.
Can you upload the .lbrn file here and describe or point out in a screenshot where this is occurring? Can you give more specific guidance with that.
