My Pro is cooling every 3-4 minutes

This is the first day I have cut multiple items consecutively. My pro is stopping to cool about every 3-4 minutes. I cleaned all the fans. Cleaned out the entire machine, and cleaned the lasers. I dont know what else to do. There are no kinks or big turns in my vent tubing to my filter. I dont know what else to try.

Your filter may be full.

I have not checked that. I’ll do that next. Thank you!

Weee you able to figure out if it was the filter that was full? I do know that using MDF tends to fill the filter faster. What you may want to do, stock up on filters if you can, so you always have one on hand as backup.

Oh no! I’m so sorry you’ve hit a snag.

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 be used when the temperature next to your Glowforge is between 60 degrees Fahrenheit (16 Celsius) and 81 degrees Fahrenheit (27 Celsius). To check, put a room thermometer next to the right hand side of the Glowforge; it draws in air from underneath, on the right.

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, and ensure that there is no fabric or other flexible material underneath it, like a tablecloth. There are air intake vents, and if they become obstructed, it makes 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 when you are not using it. When your Glowforge 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. It’s clever enough to pick up from exactly where it left off, even if it needs to pause to cool down during the print!

  • Ensure that the sun isn’t shining on the lid. This could cause the inside of your Glowforge to heat up.

  • If you are venting outdoors, ensure that extreme temperatures or humidity do not enter the Glowforge unit through the exhaust hose. Disconnect the hose from the outside air when the Glowforge is not in use.

  • Turn your Glowforge off and open the lid for a few minutes before trying again. It’s possible for the air in your Glowforge to heat up, just like a car in the sun on a hot day, opening the lid will help that warm air to escape and your Glowforge to cool down.

If you are still running into trouble, please let us know the following so that we can investigate further:

  1. If possible, place a thermometer next to your Glowforge on the right hand side and measure the temperature there; if not, estimate the room temperature
  2. Take a picture of the exhaust hose behind your Glowforge that includes the part where it connects to your Glowforge, and the part where it exits the room.
  3. Open your Air Filter and take a picture of the filter inside and send it in your reply.

Hello @brammerh12 - I’m going to go ahead and close this topic as we’ve since connected via email, and can finish up this issue via that channel. Thanks!
