Thanks for the reply! I have read your other post and watched the video a few times. I think I understand what’s going on.
So let me know if my plan is correct:
My sign will be split into 4 tiles, each 17x10.
I cut a 3"x13" piece of draftboard with an index mark engraved .5-1" down from the top edge. This is to ensure my art will be all in the usable area in the Glowforge. This will be my X/Y zero point. I taped this piece to the left edge of the crumb tray so it’s basically a fence to feed my material against.
I have index marks at the top and bottom of each of my tiles, spaced 10" apart. I probably only need two marks on the first tile and one at the bottom of tiles 2-4.
Does this sound like a good plan?
