Tool board - no response

[dutti]

hey
I try to connect my first toolboard via the tool distribution board and the expansion board... but no information from the toolboard is shwon in the dwc. I have connected tool distribution board and toolboard (can) with a thin cupper cable. I hope that's ok?
may you can help me.
thanks

@barbarossa-cologne you are running incompatible versions of main board and tool board firmware. I suggest you upgrade both to version 3.3.

[dutti]

@dc42 ok update done. thanks
Now, I have very crazy number on thermistor for tool 0.

Did you manually set V220?

https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M307_Set_or_report_heating_process_parameters

Vnnn VIN supply voltage at which the A parameter was calibrated (RepRapFirmware 1.20 and later). This allows the PID controller to compensate for changes in supply voltage. A value of zero disables compensation for changes in supply voltage. Use V0 for AC mains powered heaters. (V0 is the default. Leaving off V is the same as V0)

V220 would mean your heater is mains powered? But if that is the case, it suggests using V0 instead.

[dutti]

I did it manually

I changed the number to 0.
Same problem....

[Phaedrux]

No that's fine. And it's not related to your tool temperature anyway, it just stuck out to me.

Can you please try adding a G4 S4 to the start of your config.g to allow for the tool boards to power up before they are sent commands and see if that has any impact on the spurious reading.

Can you also check that your DWC version matches the firmware 3.3?

Can you send M122 and M122 B121 and post the results?

[dutti]

@phaedrux
After setting G4 S4 in front of the g.code --> same problem

[Phaedrux]

Can you send m98 p"config.g" and post the results?

Do you have your other tool boards connected as well?

[dutti]

@phaedrux
I don´t have the other connected, yet.

@barbarossa-cologne
Hot end fan is running.
Print cooling fan is not running.
I can´t control both.

[Phaedrux]

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

Photos of your toolboard wiring?

[dutti]

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

[dutti]

@phaedrux

@barbarossa-cologne

[dc42]

@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.

[dutti]

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

[dc42]

@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
