Print Isn't Marking Material

Follow

If your printer head is moving, but you aren’t seeing your Glowforge printer marking your material, we’ll need to do some troubleshooting to determine why this is happening. There are a few key things to check.

 

Troubleshooting Steps

First, let’s check to make sure the mirror in the printer head is installed correctly and not in the path of the beam. 

  1. Follow steps 1-5 under the heading Wiping the Mirror in the Printer Head

  2. If you see damage to the mirror or the plastic handle (for example, if the plastic handle has been melted), please check the interior of the printer head for any additional damage. If you notice anything out of place, please take a photo and include it in a message to support, so our team can help with ordering replacement parts.

  3. If the mirror and printer head look good, reinstall the mirror and move to the next steps. 

 

Next, please run a test print. To help our team determine the specific source of trouble, there are some questions below about what your printer is doing while printing.  

  1. Place a sheet of Proofgrade material in the bed of your Glowforge and open the Gift of Good Measure design.

  2. Before you start the print, please select the default Proofgrade settings for the material you are using. Once you’ve selected the material, you will see the word, “Cut”, “Score”, or “Engrave” under each step in the design.

  3. Once you are ready, push the button and start the print. While the print is running, please note your answers to the following questions:
      • Is the printer marking the material as expected?
      • Is the printer head moving during the print? 
      • Do you see a light in the laser tube during the print?
      • Do you hear any unusual noises from the left side of the printer?

4. As the print finishes, leave the lid closed and wait until the fans stop and the lid image updates on screen in the App.

5. If the laser appeared and the print was successful, the likely issue was the setting on the previous print was set too low for the laser to appear. If so, please check your settings and try another print. If the laser did not appear, please move to the next step.

6. Contact our team and let us know that your printer still isn't marking material after trying these troubleshooting steps. Before you message us, take a close look at the laser tube and check for any of the issues on this list and include a photo if you see one:

      • Do you see any damage to the inner glass tubes, such as a crack or loose pieces of glass?

      • Do you see anything in the laser tube that looks foamy or bubbly? (When normal, the coolant is clear.)

      • Do you notice any liquid in or around the printer?

Once you let us know what you find, our team will review the information you send to us and work with you to get you back up and printing!
