I’m posting this here since I’m probably the first to experience it, and it’s nice to know .
Recall my post about smoke coming through the edges of the front door of the glowforge? Well there was a reason for it. It took me a while to troubleshoot it, I’m a little slow on the uptake sometimes because I’m so naive.
I moved the machine under an exhaust hood with a total of three feet of the supplied flexible duct to eliminate the long run of 4" pipe. I still could feel air being forced out of every crack in the machine by running the back of my hand in front of the door edges. That could only happen if the interior were pressurized.
Yes, there is an intake fan also, there has to be. An exhaust fan cannot pressurize the inside. Not on Earth anyway. The exhaust was blocked causing the intake fan to exceed the output fan.
The smoke is actually a very fine particulate, and like sediment it accumulates. There is a grill just inside of the flange to connect the duct to the machine on the back. That that grill will eventually face load and restrict airflow.
I could be forgiven for assuming the thermal profile of the machine was in a state of being updated, and that was responsible for the cool-down pauses. No.
After a while, maybe years depending on usage, when the glowforge seems to be emitting more smell than it did, accompanied by cool down periods - it is time to clean that grill.
I am in the process of engraving the 2,800 side of a token and 1,400 cuts. That’s what happened.
The best test I found was running the back of your hand in front of the door seams.
That little bit of information would be helpful in the instructions - to benefit those of us who actually read them.
It will happen, it’s just a matter of time. The machine has returned to its former glory.
