The laser head on your Glowforge Aura needs a clean and secure connection to keep printing. If there's trouble with the laser head connection, you might encounter any of the following:
- A yellow button
- Aura stuck in a calibration step such as "Focusing," "Homing," or "Scanning"
- Print stops unexpectedly with an error message
There are a couple of things you can check to ensure a great laser head connection keeps you printing without trouble.
Always turn your Glowforge Aura off by disconnecting from power at the outlet before cleaning or moving parts inside the printer.
- Disconnect your Glowforge Aura from power.
- Open the lid and move the Laser Head to the center of the rails.
- Lift your laser head off the magnetic dock.
- Grasp the black connector at the back of the laser head. Pull back on the connector to unplug it.
- If you see buildup on the fan blades inside the head, perform the steps in our guide on Air Assist Cleaning.
- Check the connector on the laser head cable, as well as the cable plug on the laser head itself. Compare to the following photos:
If your cable connector or plug look different than the photos above, please take a photo. If components look damaged, please continue to step 10.
- Plug the cable back into the laser head, taking care not to twist the cable. Once plugged in, it's normal for the cable connector to be able to move back and forth just a bit.
- Place the laser head back on the magnetic dock, with the cable connector to the rear and the Glowforge logo reading from right to left. It should snap into place.
- Try another print.
- If you're still experiencing a yellow button, stopped prints, or stuck calibration after following the steps above, there may be a hardware problem with your Glowforge. Please contact our team and let us know the following:
- What type of materials have you been printing on prior to the trouble? For the last 30 or so prints, have you been printing on one material more often than others?
- What troubleshooting steps have you tried?
- Attach any photos you've taken, such as the one in step 6.
- If you're receiving any error messages, let us know what the message says, and when you last saw it.
