On a two hour engrave for 3 travertine coasters, about a third of the way through the file the head stopped moving. Fans were still cranking. First thought was a cool down, but there was no Amber button and no message in the UI. Button stayed lit white the whole time.
I waited 45 minutes while the machine whined away. Finally I gave up and decided the job was trashed so I was going to cycle the laser, but for lack of anything else to do, I pushed the button, and bam - it started engraving right where it stopped!
It happened twice more during the job, and immediately pushing the button again started it right up. Weird.
I know it wasn’t a temperature issue because it was cool enough in the shop to prompt me into wearing a light jacket.
Just a heads up if you encounter the same behavior, don’t give up on the job before you try pushing the button again!
I reported the event with date, time and time zone so the logs could be checked.
BTW, my forever unit is due to be delivered Wednesday, and I am looking forward to experiencing a production glowforge - and feeling a bit sad that my time with the pre- release is coming to an end.
