I would like a button on the UI to be able to turn the exhaust fan on and off. It would also be nice to have a timer in seconds associated with the fan button. This would be useful when I have cut acrylic and really want to clear the laser cabinet of any of that nasty smell before I open the lid.
And B.T.W. GF team thank you for building an awesome machine. I had only imagined that I would use it for some projects but as I get to know the GF I expand my projects every day. This machine just rocks!!!
I think he was referring to the air assist fan on the gantry. I was eyeballing the fan lead last night. A switch on that line, or a speed control wouldbe sweet.
Absolutely, thanks for the caution. Extra vigilance would be required for that reason. I noticed you have an extinguisher next to yours, as do I, but I haven’t seen anything I couldn’t blow out or snuff with my thumb. Next option would be to smother it with a rag. After that the squirt bottle. Extinguisher as a last resort.
@palmercr, I thought of blocking it last night, but decided against it because 1 - I didn’t know how that would affect the fan motor, and 2 - it’s not my machine.
When you block the air flow to a fan it no longer has to accelerate air and push it forwards. It just rotates the air already in it and once that is moving there is little work to do. So contrary to what you might expect, blocking a fan lightens its load. You can hear the revs go up.
