The last couple of times I have had the glowforge on it results in a Cooling Alert error after running it for more than 30 mins.
If I run a print for longer than that half hour it pausing with a cooling down message. After turning it off and waiting a while I turned it back on and all it read is “Alert Cooling” with an amber button.
My unit has been in my office with the same temperatures for years now with no issue.
I have included the pictures I think you will ask for to troubleshoot this problem.
Thank you for your help!
