I finally got a chance to try one of the images from Gantryco. It's not all that bad. Tomorrow I'm going to borrow the micro sandblaster and see if it looks better when I knock down the nubs. Something went wrong and made that line. I think my motor power supply started to fail because it is under rated for current output. I walked away a while later and came back to find the stages completely stopped and the laser was firing 100%. It burned a whole all the way through this 1/2 inch thick piece of Cherry.
These were images I prepared myself for 3D engraving.
