1) Check if Your Lid is Open
If your lid is open, the switches will not be triggered.
2) Check if Your Laser Cutter is on an Uneven Surface
If your surface isn’t level, one or both of the lid switches might not be activated.
3) Check the Small Sponges on your Laser Lid
If they are cracked, damaged, or worn down, they might not be triggering the lid switches.
4) Faulty Sensors need Repair
If none of the previous solutions fix the error, and physically pressing both sides of the lid down so the switches are activated does not turn the icon white, then one or both of your lid switches are damaged/faulty and your laser needs to be serviced.
