Glowforge Red Wire High-Voltage splice repair tips 

I put that over the electronics when I was doing some engraving/scoring on plaster of paris pieces to keep any dust off the electronics. I made sure that the cardboard clears all the moving parts and no, I haven't had any problems with it being in place :)

On my Glowforge, the red wire on the left side (away from the on button) is permanently attached into the power supply. I cut the red wire at the place where it shorted, put the splice kit in line and then ran the wire around the back of the glass tube as shown in this video. The right hand side of the wire (the side where the ON button is located) will have a ring terminal attached to it from the Glowforge factory. That ring terminal screws into the end of the glass laser tube. You have to remove the red silicone cap off of the right side of your laser to get at this screw. It is a 10m hexhead screw. Here is a link to the video I started with ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rdnKwaaekTY.html&pp=ygUSZ2xvd2ZvcmdlIHJlZCB3aXJl
