I had this same issue recently and Glowforge replaced it. I’ve had the replacement machine since Tuesday, so its only been 5 days and its now doing the same thing. I wonder if its a wattage issue in my she shed. I’m having an electrician check it tomorrow, but wonder if anyone else found that that was their issue. The original machine was in our garage for 9 months before I got my shed. It worked well up until the beginning of August which would put it working in the shed for 1.5 months.
Double check your power setting. Sometimes it defaults to ‘1’ which won’t do anything…but the head will continue moving as if it’s working correctly.
@chammonds I am so sorry your Glowforge printer laser is not appearing. It looks like you sent us an email regarding this issue. I’m going to go ahead and close this forum post and follow up with you there.
