Blurry camera / can't scan PG QR codes

My camera is blurry and is unable to scan proofgrade QR codes. This also leads to unreliable positioning of engravings (unless I’m cutting out the project in the same operation). I don’t have snap marks so I rely on vision to position images.

Looking in other threads the resolution seemed to be for each user experiencing a problem to create an incident report and have GF support look into it.

Correct. This post in Problems and Support opened a ticket for you.

Some things that you can try while waiting for support to respond are to clean the lid camera if you haven’t done so yet, check it to make sure it is not loose - it should not turn, and it also helps with alignment issues to run the Lid Camera Recalibration .

I admittedly only gave it a cursory wipe down. I didn’t realize how in-depth the cleaning process is, so I’ll go through that next.

How frequently should I be going through all the steps on that page?

It varies by how often you’re using the machine and what material you’re using it on. I generally have to give it a good wipe down a few times a year. I think the general recommendation is every 40 hours of use. (Actual time spent cutting and engraving)

I’m so sorry for the trouble with alignment! We’d like to have you try a few troubleshooting steps for us:

  1. Turn off your Glowforge.
  2. Check for small pieces of debris or dust.
  • Check the lower door to make sure it closes all the way. It may require some force to open, but open it, wipe any dust off the edges, and close it all the way.
  • Remove the tray and clean any dust or debris from the surface underneath. Pay careful attention to remove all debris from the four dimples where the tray rests.
  • Check the lid to make sure it closes all the way. Small particles of material, such as dust or debris, can prevent it from closing completely.
  1. Check the surface your Glowforge is on to make sure it’s flat. Ensure it is not twisted slightly and that there is no debris propping up one side of the machine.
  2. Turn your Glowforge back on.
  3. We included an extra piece of Proofgrade Draftboard with the shipment of your materials for troubleshooting. Place the Proofgrade Draftboard in the center of the bed and print the Gift of Good Measure using the default settings.
  4. When the print finishes, leave the lid closed and wait until the fans stop and the picture updates. Without moving your artwork or your material, take a screenshot of the Workspace to show us the difference between the artwork placement and the actual print placement. Make sure to include the rulers in your screenshot and show as much of the bed as possible.
  • Mac: Press Shift-Command-4 and click and drag a box around your image. You’ll find the screenshot file saved on your desktop.
  • Windows: Click on the Start Menu and type “snipping tool”. Open the Snipping Tool > New then click and drag a box around your image. Click the Save icon and name and save your file.
  1. Send us the screenshot along with the date and time of the print, and we’ll investigate.

Thanks for reaching out Michael. I’ll keep an eye out for the material troubleshooting shipment. In the meantime I’ve followed all steps in the cleaning/service/moving webpage. That didn’t fix the blurry camera issue. I’ll print the gift of good measure when the draftboard arrives.

Thank you for following up @ejola. I see you already emailed us about this and we are going to follow up with you there, so I’m going to close this topic. If you have any other issues please feel free to start a new thread or email us at
