Flashing then solid orange light


#1

I was able to make one print a a few hours earlier went to do another after making a change in the design. It got stuck in a calibration cycle so I powered off to reset. When it came back up it flashed the usual white then heard the usual clicking as if it were going to calibrate no movement then flashed orange 3 times then solid for a few seconds and off. Tried it again this time manually moving head under Camera with same results. Is there something else I may have missed?

How cold is it in the room? Is your vent open so that cool air comes in? That might be an issue.

I’m sorry to hear you ran into trouble. It looks like your Glowforge paused due to warmth.

Your Glowforge Pro features a closed-loop liquid cooling system that uses the air from the room to remove heat. It’s boosted by a solid-state thermoelectric cooler that allows for heavier use at higher ambient temperatures than the Basic. It is designed to print in an operating environment between 60 degrees Fahrenheit (16 Celsius) and 81 degrees Fahrenheit (27 Celsius). 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 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!

If this recurs or you have another question, please post a new thread!
