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.
Check if the white ribbon cable has come loose or fallen out of your print head. If it’s disconnected, the button will stay orange until it’s reconnected.
It’s been a little while since I’ve seen any replies on this thread so I’m going to close it. If you still need help with this please either start a new thread or email support@glowforge.com.
