I ran into Danny last night as he was cleaning the optics and debugging the system (nice to meet you @dannym !) and used the system after the repair. He tested the laser after the repair and it worked, but when I went to run the laser I got an error message “Please install the cone before using air assist.” and the laser would not operate.
Danny mentioned that there is a switch the machine uses to detect the presence of the cone and that if the cone fully triggers the switch then the cone actually blocks some of the beam. Unfortunately when the cone is in the correct position the switch is close to its switching point, so a small perturbation can lead to an erroneous indication that the cone is missing even though it’s actually installed properly. With that in mind, and given Danny’s successful test just a few minutes prior, I tapped on the cone a few times with my finger and the error resolved.
The laser appeared to work normally after that but I don’t have enough experience to tell if the output was somehow diminished or abnormal. My cuts were consistent and to spec for the rest of the time I used the machine, so I assume it was operating normally again. I just wanted to let you guys know in case the error reappears and to help troubleshooting in the future. My taps were pretty gentle so I don’t anticipate I caused any misalignment but it’s always a possibility.
