Yeah, that's what I was thinking... don't we have some runaway protection via the RTD anyway?

I just got a nitehawk, but don't have a 3-wire fan for my hotend... Now you're making me rethink that. I've never had a problem, but now that I know the possibility exists, I'm worried 🙂

...Okay, but there's nothing implemented by default?

So, I take it this is half of a voltage-divider somewhere? Can you point me to something that explains the circuitry in more detail?

It's very useful for hotend fans as you'll then be able to tell if it's stalled...but the question is: does RatOS/Klipper automatically recognize the rpm pin and implement some kind of warning if the fan is not running? ..or is there some extra config required?

I had the same question; got my answer here:

...but I don't know whether klipper is 'regularly checking'. That's a good question.

found it in klipper docs, but it's thin on detail:

looks like it's related to a reference voltage.

What does this 'sense resistor' setting do?
My orbiter motor got fried, but it was an older one that should have been operating at .35. Could this sense resistor business be realated as well?

(figured it out at the same time you did; came here to trumpet my success, only to see you'd already thought of that 🙂

I've added to my printer.cfg for now, and am no longer getting klipper shutdown errors.

So, should that go in the board definition or something?

The nitehawk has a 2.2K resistor; the default is 4.7k

..raw reading at the plug measures about 1.1k, which corresponds to 26C/78F.. so the sensor itself seems OK.

Now I'm getting ADC out of range:
MCU 'toolboard_t0' shutdown: ADC out of range
This generally occurs when a heater temperature exceeds
its configured min_temp or max_temp.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown
...
I have a PT1000 RTD.
relevant settings seem correct; doublechecking wiring.

Sorry... false alarm.
My beacon firmware was out-of-date too; that was apparently the gating item.
Fixed.
