I turned my glowforge pro on and did a test run of 3 min, it’s been on for an hour not doing anything and I went to do a second run and the button turned orange. I turned the machine off to let it cool down but I wasn’t doing anything so I’m not sure why It would have been over heating. It’s well vented in about 70f ac garage.
On another note,
When I turn the glowforge on the fan starts at full power with an in-line fan attached.
