Oh no, I’m sorry to hear about the trouble with your Passthrough prints.
While we investigate the circumstances around the error, would you perform a test print for us?
The design we use has some known dimensions built into it and it will help me extract logs afterward to take a closer look.
Here are the steps for the test:
Load a sheet of material into the Pro Passthrough slot and ensure that the portion sticking out of the printer is supported so the material lies flat on the crumb tray inside the printer.
Double-check that the material is completely flat against the crumb tray. A quick way to do this is to press gently on the material where it rests on the tray and feel if it moves. If not, you’re good.
It can help to use pins to hold the material flat against the tray. For example, a lot of customers use small pieces of scrap to print these pins available in the free laser design section.
Open the Smooth Curves Stencil from your design library.
Turn on the Pro Passthrough feature in the menu bar.
Select the entire design, and arrange it so that the dotted line at the top of the work area is at the tips of the arrows in the design
Click Print and run the first section of the design.
After the first section completes, move your material through the Pro Passthrough slot so the printed area is more than 3 inches away from the front of the Glowforge.
Follow the prompts and run the 2nd portion of the test print.
