Hey guys so just recently my glowforge starting acting funny and im not sure if I have an issue or if this is just common. It has to stop multiple times during a print to “cool down”. It sometimes even does it before it even starts the print. I did a quick 3 minute print and it actually had to stop twice with the message:
“cooling, we’ll automatically resume your print in a minute or two when we’ve cooled down”
It was only 77 so I dont think it was an outside temperature issue but idk. Anyone of you long time GF owners experienced similar issues? Ive only had mine since January.
Put fans to blow on the front right corner where the fan inlets are, or cool the room more, or figure out a way to blow cooled AC air at/into the GF. The GF Basic is only rated to 75* F and the GF Pro is only rated to 81* F.
We had extensive discussions last summer when we first encountered temp issues in the PRUs.
You need to keep ambient air temps within the specified range or you’re going to see a lot of pauses and orange lights.
The lower end is important too - they want 60F as the minimum operating temps. Some of us are using reptile cage heaters to keep it warm when the ambient air temp in our basements or garages are under that.
Your Glowforge Basic features a closed-loop liquid cooling system that uses the air from the room to remove heat. It is designed to be used between 60 degrees Fahrenheit (16 Celsius) and 75 degrees Fahrenheit (24 Celsius). Learn more about the operating environment here. Printing outside these ranges may cause your unit to pause before starting, or to pause periodically during the print for cooling. This isn’t harmful, but it can make your print take a little longer.
You can try any of these things to improve warm-weather performance:
Try printing with no material on the bed (so as not to generate smoke and fumes) and no exhaust hose attached. If this works, then the problem may be that your exhaust hose is constricting the flow of air out of the unit, preventing cooling.
Examine the bottom-right side of your Glowforge. There are air intake vents, and if they become obstructed, it could make cooling less effective.
Try pointing a fan at the right side of your Glowforge. If there is warm air around the intake, this could help it cool off.
Power off your Glowforge and allow it to cool, then power it on and print immediately. When it sits idle, the fans are off, so heat can build up.
Just wait. Your print may take a little longer when it’s warm, but your Glowforge will protect itself and make sure it cools enough to prevent any loss of power or damage. And it’s clever enough to pick up from exactly where it left off, even if it loses Wi-Fi during the print!
Thanks for letting us know about this! If you continue to see this behavior after trying the above, please start a new thread or email us at support@glowforge.com.
