Air light flashing red

Scanner & Falcon
1

Hi, I received my Falcon 2 22W machine this week and have only had time to test it on 2 cuts on various thickness of paper in lightburn, all was good.
Now, upon starting the machine it goes through its sequence of flashing green lights, beeps and running air. Once done, the air light flashes amber once and continues to flash red, both others remain green.
There is good airflow through the tube and laser module.

Now it will not connect to my computer anymore.
It does not show up in the USB list of connected devices on a MacBook.
Macbook no longer asks me to allow the connection from the device.

I am not troubleshooting the Mac side as I imagine the flashing red Air light is the culprit.

Help please

Thanks,

So since no-one has chimed in on this I’ll post my finding that I was wrong about the flashing red light as it’s in its normal state when the air has stopped ( even in standby without a program running )

I resolved my issue only after re-flashing the firmware on the unit twice and the laser unit once.

Hopefully it sticks this time.

Hello @Gcap ,

Glad you could join the Creality Forum…!!! Welcome… :wave:

I’m glad you found what was going on with your Falcon 2 22W and also Thank you for sharing that as someone else will most likely have the same questions…!!

I ended up with the 22W and the 12W (ordered the same week when the former ended up on sale at the same price as the latter, but I’d planned to return the 12W once received). The 22W turned out to be refurbished but nowhere did it state that this would be a refurbished unit. You can just see the muck in the the air filter, the scratches from wear and tear, etc. It’s highly disappointing. The 12W, while is brand new (or so it seems) is giving me the same error as the 22W which is the same error you’re getting. I’ve tried reflashing the firmware; I even changed SD cards just to see if that was the problem. Both the 12W and the 22W are doing it. Different machines, different frames, different modules, different air pumps, same problem. I have walked through this process over and over and over and over. Video after video, manual after manual, message board after message board. I can’t find the root cause! Please help. How did you get the machine to reflash the firmware and keep it??
