I’ve had my glowforge for just over a year and have had 1 replacement unit sent. I’m using a refurb Plus unit that has been perfect up until this morning.
Today I did a basic clean of the lenses before running a 49 minute engrave. About 12 minutes into the engrave I noticed a quiet mouse-like squeak. After the 3rd time I went over and looked at my glowforge and noticed that not only was the squeak coming from the machine, but as the squeak was happening, the laser head box was actually lifting and bumping out a bit. I let the print go on a bit longer but after hearing it about 4 more times (they got progressively louder and the bump became more pronounced) I stopped the print and am now trying to troubleshoot the issue. I removed the printer head and then moved the mount back and forth very easily past the spot where it was jumping around. I moved the gantry back and forth with no problem. I blew condensed air into the whole thing in case a small piece of something was caught on the belt where I couldn’t see. I even pulled the belt down and didn’t see any missing teeth or any debris on the belt anywhere. Any other advice before I give up and wait for ever for customer service to help? Thanks yall!
