Tool board - no response

[Phaedrux]

How is the PT1000 connected?
Is it actually a PT1000?

Photos of your toolboard wiring?

It's the original tool changer thermistor.
Is it a pt100?
Oh no...

@barbarossa-cologne I've seen that crazy temperature value once before when a tool board was configured for a PT1000 sensor but the sensor wasn't connected.

@dc42 that's what I checked another time 2 minutes ago. It's definitely connected.

@barbarossa-cologne have you measured its resistance, to verify that it is a PT1000, not a PT100 or a thermistor?

[dutti]

@dc42 connected a different thermistor = same problem

[dutti]

@dc42
Yes. Now I connected a typical Chinese thermistor and it shows the same number for temperature:/

@barbarossa-cologne the config.g file you posted was for a PT1000, not a thermistor. Specifically, this line:

M308 S1 P"121.temp0" Y"pt1000" R2200 ; configure sensor 1 as PT1000 on pin 121.temp0

@dc42
Eeeehm ok.
Yes
That was the problem...
SOLVED
