I recently had a problem with my glowforge where any boxes that I cut wouldn’t fit together. I cleaned all the rails, checked the belts but it didn’t fix it. I ordered a new carriage plate belt but that didn’t help. I printed the gift of good measure and emailed support. The folks at support asked for lots and lots of pictures and many more prints of the gift of good measure. After a month of help they finally said that they were out of options. Due to the glowforge plant being moved from Mexico, they recommend that I contact Wiregrass Technology. I had heard of them but had never looked to see where they were located. They are in Dothan Al, which is 150 miles from Pensacola Fl where I live. I took my laser to them and 2 days later they called me and said that it was fixed.
When I picked it up the technician asked if my glowforge was ducted outside continuously. I said it was and is located in an airconditioned garage and ducted through a vent in the garage door. He explained that the left hand pully on the carriage plate belt had rust and crud in the groves that the belt fits in. He also asked me if I had a blast gate, which I replied no. The consensus is that the moisture which is prevalent in Florida combined with the glowforge being kept cool caused condensation which caused the rust and crud buildup on the pully. I now have a blast gate. Hope this will help someone else avoid the same problem.
Lastly I would like to mention how impressed I am with Wiregrass Technology. My laser was returned to me looking like new and the total cost was $375, plus 2 tanks of gas. Their facility and staff were really impressive.
