I am loving my new fiber laser. I have noticed though when engraving bitmaps it is still firing on white objects...ever so slightly. So, if I have a bitmap that is round, but square file, it fires in the white part and you can see an ever so slight change in the surface. Have a missed a setting in EZCAD?

follow the instructions in the screenshot-- raising the number raises the 'engrave white' threshhold. Experiment until you stop engraving the background and still keep the detail you want.
-- I haven't had much experience with photo engraving on these things yet, but I have found out this helps with not engraving white!

Thanks so much! That did the trick.
