Engraving glass problem?

vendredi 27 février 2015

I am attempting to learn how to engrave on glass, and right off the bat I noticed vertical lines down the glass in the same spots down two totally different pictures I sent over to the engraver. I'm hoping it's me not my Trotec speedy 300. Then I tried to see what it would do at the other end of the playing field and got lines as well. :confused: Anyone got any Ideas? Here are some pics...DSC00003.jpgHere are the two totally different pics lined up.DSC00002.jpg
