Not sure how to word this error correctly. However, I have been engraving photos reasonably successful (hit and miss) for a little while. 2 weeks ago I began to get single either missing or heavily burnt etched lines across my photo engravings. becoming more frequent. The lines are usually either at the bottom of the photo or 2/3rds of the way up. I have asked Domenic from Darkly Labs if they have had others with similar but at this time nothing but he is going to look at the GCode of one of the file for me. He suggested perhaps someone here may have an idea as to the cause. My original settings with success are:
Emblaser 1 A3 - 4W
Feed - 130 in/min
FRC - 20 -25%
Max - 240 - 230
Min - 5
Res - 0.006
I was using a Step over of 0.1 much earlier when I first bought my laser but had problems with noticeable lines across finished images. I have since changed again on the advice of Domenic from 0.006 imperial to 0.007 and had success with 1 image so far. However I would still like to know if this could be either Software, Hardware or OS related, I hate puzzles.
Any suggestions extremely appreciated thank you.
