Is my GF BROKEN? Unwanted LINES running across my engrave

  1. I assure there are NO lines running across my text.
    Its just a simple font text from illustrator, and created outlines of the text to engrave. Nothing fancy. Added some star themed artwork, again nothing fancy.

See photo 1.

1st attempt. Ran first print, and ruined a perfectly good PG material, these lines showed up for no reason, had to cancel print. (Photo 2)

2nd Attempt, I find another PG board, and put the artwork at a diagonal instead of horizontal. This time I paid attention to the red preview screen before hitting the print button and noticed the LINE shows up! Noticed how it only shows up going horizontal! Weird huh? Why is this happening?

3rd attempt, I power cycled the GF. Restarted the GFUI, reuploaded the image.
NO LINE in the red preview, cool. So I hit print.

And guess what, even though it did not show in the red preview before print like the photo above, the 3rd attempt was a failure, the LINE shows up on the engrave. Had to cancel print.

SO FRUSTRATED, I wasted 2 perfectly good PG materials and now I dont want to print anymore, scared anything will just have a line through it.

Any tips or suggestions guys?
