I didn’t want to run a big print through the printer for just testing the passthrough, so I loaded in some blank chipboard along with a small spacer that I had cut on the mat cutter from some scrap. Cut it by hand. Yup. Why the *#^% did I buy a laser again!?
Taped the spacer to the rail and set up a quick 500-piece puzzle in Illustrator. Broke the design down into 3 sections of 8” and sent her to the Glowforge. Oh - along with a small line that I scored on the spacer for alignment. Cut. Slide. Cut. Slide. Cut. Slide.
Worked pretty good. The max I was off on sliding the uncut piece up for the next cut was about 1/16th of an inch.
I measured the spacer and left about as narrow of a margin as I could between the cutout and the puzzle, which you can see on the left side of the image.
Now, I own the puzzle from hell. A 17 3/4” x 23 1/2” puzzle with nothing on it. I gave up on assembly. Will sell at a discount to whomever wants it. Great gag gift?
