If you detect a strong, sharp smell that also causes eyes, nose, or throat irritation, or visible smoke escapes your Glowforge while the lid is closed, your Performance Filter is not operating properly.
If that happens, stop using your Performance Filter and follow these instructions.
- Ensure your Performance Filter is turned on before every print and left running until the print is complete.
- Ensure that the exhaust hose is securely connected to the Glowforge printer and the Performance Filter.
- Ensure that the Performance Filter is enabled in the Glowforge App. You will only need to do this once. After it is enabled, all users will have it enabled from that point forward.
- Make sure that when you turn on your Performance Filter, you turn it on to the right setting. If the fan is moving too slow or too fast, the filter will not work properly.
- Make sure the hose is connected properly, with no more than three 90-degree turns.
- Make sure that the materials you are using are laser-compatible. The Performance Filter has been tested with Proofgrade materials; it may not remove smoke and fumes caused by other materials.
- Change the filter cartridge. If you have been printing for a while, it may be time to replace your filter cartridge.
- Inspect all four latches to be sure they are tightly closed.
- Check the hose to make sure it is not kinked, squished, or twisted.
- Remove the hose and inspect the inside to ensure it is not obstructed.
- Try the steps outlined in the article Reduce Odors.
If you have completed all these steps, you are using a new filter on the correct setting, and you are experiencing eye, nose, and throat irritation when using Proofgrade materials, stop using your Performance Filter and contact Glowforge Support.
