Bypassing the front door open warnings can be done by using magnets to trick the sensors into thinking that the lid and sensors are in proper alignment (lid-mounted sensors and door-mounted magnets), or you can simply install a bypass jumper that tells the sensor circuitry that the door and lid are properly aligned. If you’re interested in attaining a set of bypass jumpers (non-invasive to the Glowforge wiring and fully reversible) message me for more info.
