topic_unsolved Fan tacho readout
While reading through the forums, I came to believe there is a way to connect a fan tachometer output to the Duet 2 Maestro in order to get a speed readout. I connected the pin to EXP_0 using a 1N4148 diode, cathode (black strip part) to the yellow wire, anode to Duet. Is there more to it than that? I can't seem to find the readout anywhere in the web UI.
RRF 3.01-RC6, DWC2.11

should have to configure both the fan output and input with m950
M950 F2 C"!Fan2+exp.pb6" Q25000 ;
see rrf3 notes for
Thanks! Should I use a pullup on the input pin?

i'd expect so as the tach output is usually open collector. you might have to adjust the pin name to fit the maestro as well.
Thanks, I got the readout now! Now to just solve the little problem of it always being zero
