I would like to know what the flashing orange light over the triangle with an exclamation point means on my SafetyPro AP2. I tried looking at the manual, but that error doesn't exist. I used my M1 Ultra for the first time last night, and I couldn't tell if the filter was working the way it should. I could see smoke being pulled away in the laser cutter, but the room smelled very strongly of smoke after one small project. I also didn't hear it making any sound, so I was curious to know if you should be able to hear it running. I've already double-checked the filters, and they're all installed correctly with the visible line at the bottom.
