Duet Maestro R19 Resistor off

Veti

Hi

My PT1000 Sensor started to show 40C at room Temperate. It used to show the correct value

At first i though the Sensor might be broken. But then i connected the Sensor to the E1 Thermistor header and it showed the correct value.

I then measured the Resistors. R53 and R15 both read 2195, but R19 read 2075.

Have there been reports of degrading resistors with the duet?

We haven't had any such reports, on any of the Duets.

at least one https://forum.duet3d.com/topic/7752/solved-thermistor-pull-up-resistor-is-off-maestro

I'd forgotten about that one!

i suspect that most people will either be running pt100 or normal thermistors.
there around 100 ohm will not make a big difference.
i adjusted the resistor value in the m305 and its working as expected.
