Over the last few days, I have experienced stopped prints repeatedly due to error message “Sorry - it got too hot for printing”. The button glows yellow whenever this happens, and always says “Print Stopped”. I have raised the Glowforge up and placed a fan in front of it to improve airflow, and cleaned the exhaust fan of dust and debris. After letting it cool overnight, I experience this same issue within 10 minutes of a print. I have had others indicate that there are sensors inside the machine on the left side behind the exhaust fan that can become caked in dust and register false temperatures. The ambient temp outside is 70 degrees and cloudy, my house is set to 68 degrees. The Glowforge isn’t even close to warm to the touch anywhere on the machine, the room is cool, there is good ventilation under and behind, no sunlight is hitting the machine, and the print fails very quickly. After the print stops, it says “too hot for printing”, buffers and says “cooling”, then it says “Focusing the head of your Glowforge” and buffers while “focusing” without ever actually focusing. It has yet to continue to print after this malfunction.
The area around the circuit board and coolant reservoir are pretty dusty still, but the exhaust fan has been cleared of debris. The radiator and fan under the right side appear to be quite clean apart from minimal dust. I have attached an image of the circuit board area.
If there is anything that can be done to remedy this as soon as possible, I’d be very appreciative. I am very much in need of my machine for a product drop this Friday.
