Passthrough issues

I have been having some passthrough issues. I’ll get an error stating that the print didn’t complete. Also an issue that after the first print is done it goes to the lineup of the 2nd print and doesn’t allow me to move the board first. I ruined so many boards with what ever this glitch is that I just stopped using my passthrough. 2 weeks or so ago I didn’t have any issues at all running the passthrough. Pretty upsetting. Anyone have any ideas on how to fix this? I calibrated it last night and will try something again today but I don’t think that it will solve this issue.

Hello, @laabsdawn thanks for reaching out on the forums! I’m sorry to hear about the trouble you are running into with your prints. I extracted the logs from your Glowforge to investigate the problem, and it seems like your unit is running into trouble during the calibration step in which the lens focuses inside the printer head (you may hear this when it’s happening - there’s an audible “ticking” sound as the lens moves up and down in the head). There are a few different reasons this error may be occurring. Could you please check a few things for me to help narrow it down?

  1. Check the printer head lens by following steps 1-5 from these instructions: https://support.glowforge.com/hc/en-us/articles/360033633614-Cleaning#things-that-need-wiping. If you see anything unusual such as damage to the lens or debris in the printer head, please take a photo of it and attach it to your reply

  2. If you are using magnets to secure material to the crumb tray of your Glowforge, please remove or reposition them and try again. Magnets placed close to the printer head may cause trouble during calibration

  3. Check the connection of the printer head to the white ribbon cable in the printer arm. Turn off your Glowforge, unplug the head, and plug it back in. Note whether the cable plugs back in securely, and whether you feel it “click” into place


Let us know how it goes!
