Thanks @markwal!
With regards to printing on materials provided by other vendors, unfortunately, I don’t have any guidance. It’s very common for materials to perform inconsistently in a laser. However, Proofgrade materials should print perfectly every time. Should you find a problem when printing on them, please let us know right away.
I was about to move this to Beyond the Manual so the discussion can continue there when I saw your post here: Shifting image?. That made me want to double check - have you had other prints in which shapes haven’t lined up with themselves the way you expect - like the lines in the star in that image? If so, would you please:
- Turn off your Glowforge (this is important to avoid damage to your unit)
- Open the lid and, using both hands, gently move the laser arm to the center of the bed
- Gently move the head under the lid camera
- Put in the crumb tray that we provided
- Turn your Glowforge back on
- We included an extra piece of Proofgrade Draftboard with your materials shipment for troubleshooting. Please print the Gift of Good Measure on Proofgrade Draftboard in the lower right hand corner of the bed
- Let us know the result. If the print looks incorrect, please include a photo.
