Thanks you C0 parameter was the problem.

When I use this setting for an emergency button, the board locks when it is working.

Is correct it?

M950 J1 C"!^exp.heater4" ; Stop buttom pullup active low
M581 P1 T0 C0 ; Emergency stop on trigger anytime

@dc42 said in Back with opnpnp again:

@qlfecv, the M308 documentation for Linear Analog sensors was wrong. The min and max reading parameters are B and C, not L and H. So use B0 C4095.

Working fine

In Barcelona, Spain

Ok, so I try it.

@dc42 what is the best option to add the sixth axis?

I don't like using additional hardware, but with duet2wifi I have no other solution.

When I can I will buy one " Duet 3 Main Board 6HC".

I don't understand that I'm doing wrong.

I have this configuration

M950 C"bedtemp" C"nil"
M308 S2 P"bedtemp" Y"linear-analog" A"V_Sen_H2" F1 L0 H4095

The pin is 0V I send this

echo sensors.analog[2].lastReading
0.0

Now pin 3.3v

echo sensors.analog[2].lastReading
100.0

Thanks again

@dc42 Is posible read digital value? (4095)

Thanks @dc42,

Yes, I want shorter response.

How work M409 with M308 sensor?
