Unknown command:"BEACON_RATOS_CALIBRATE" and 4028 fan not working
When I run BEACON_RATOS_CALIBRATE it gives me this error, I can also not update anything even after clicking check for updates multiple times.
My 4028 fan is also not working, the connection is fine and I have set the voltage correct on the right fan connector. I did accidentally connect the tacho to the pwm pin on the toolboard for a while though, did I kill it?

I'm out of town, so ability to help is greatly reduced. Did you follow the update procedure as outlined elsewhere? Search posts by me and you'll probably find it, it's about 15 steps long.

it also does not recognize the fan

That may have killed the fan, yeah
The 4028 fans run at 100% if they aren't getting a pwm signal, so if they have power but aren't running then it is a good bet they are toast.
Surprisingly it has survived
I still can't update RatOS nor use the BEACON_RATOS commands though

I will try if it happens again, for now I'll just resume with hardware calibrations and reinstall RatOS completely
It managed to execute fine when ran via OctoApp
strange..
