New user to both Lightburn and laser engraving. I recently bought some .DXF files off Etsy. Opened them in Lightburn and did a test run and liked most of the results. I started converting them in Lightburn to .LBRN files. I later went to run a .LBRN file with unsatisfactory results (engraving too deep, charred). I performed basic maintenance on the machine (cleaned and aligned the mirrors).
I realized when I drag a .DXF file into Lightburn, it does not bring in the speed and power settings from the file, but defaults to 175mms and 25% for black lines, 10mms and 40% for red. Every .DXF file defaults to this while .LBRN files open just fine. Any idea?
There is a setting someplace that keeps you last settings.
Depending on what you do, that could change for the next file you think should work.
I have found some files that are just messed up for that reason
Always check the settings.
