My GF is stuck in cooling down mode… it started the first cut of the day and did about 5 cm before going into cooling down mode… it did sit idle for 20 minutes before starting
It is not a hot day
Current room temperature is 20 C
The cable to the printer head is securely in place
There is no blockage to the vent on the right side underneath
The filter at the back it totally clear and blasting out air
The exhaust hose goes horizontally straight to outside and is completely clear, no bends or blockages
It’s been in cooling down mode for over 20 minutes a couple of times
The laser head is not hot
I have switched off and restarted several times
This is a refurbished machine
There is no excess smoke
Same material as I’ve been using since I’ve had a GF 2 years
20ºC seems like it should be cool enough…the temperature that really matters is not the head, but the fluid in your reservoir, so if you’ve been doing a lot of lasering and it’s a basic model, it could theoretically have gotten warm enough to throw an error. There could also be warmer air coming in your vent hose, making the internal temp higher than the ambient temp in your room. If you have a thermometer you can stick inside the closed machine it might help to see what the temperature actually is nearer to the cooling fluid.
There’s also a chance you could have a bad temperature sensor. Support will be along soon to weigh in, hang in there!
I’m so sorry to hear that you’re running into trouble. I’ve extracted the log files from your Glowforge to review your most recent prints, and compared it with the details you’ve provided. We’ve made a small change on our end. Could you please reboot your Glowforge and perform an additional test print and let us know how it goes?
We’ll make sure to keep the thread open until we’ve heard back!
It did start working the next day… but today it’s back with the cooling warning… I can feel nothing that can be comprehended as warm inside the gf… I have only done a few cuts this morning
Are you able to do the same this as you did last time?
I have switched the printer off for 3 hours and returned… switched it on again and then it had trouble centring the head… switched it off again, moved head to the front, switched on again and it centred fine but then repeated same cooling problem
Just so you know you missed out the photo that comes after “Reach over the laser arm, and to the left of the inside of the unit and you’ll see this circuit board:”
Unfortunately, it looks like your unit is experiencing an issue that we can’t resolve remotely. I want you to have a reliable unit, so I’m recommending we replace this one. I’ll be in touch via email to sort out the details. I’m so sorry about the bad news.
A thermometer will give you more accurate feedback.
