Try zooming out on the bed to see if the lines appear. I’ve had many a line disappear at high zoom, and reappear after zooming out and back in.
Nope, the missing line didn’t engrave at all. And, another line started out bold and crisp, and then gradually disappeared (see photo). Help!
Hmmmn. Can you zip up your AI or SVG file and load it here so I can take a look at it?
I figured it out. I closed the Illustrator document and reopened it, and then the lines matched what the GF was seeing. I just need to go in and manually fix them in Illustrator. I’ve never had that happen before! Thanks for your willingness to help!
