DWC 3.2.0 beta-1 Incorrect tool temp at start up

DWC 3.2.0 Beta-1

DWC is reporting the tool temp incorrectly at first start up, its NOT listing a heater fault and there is 100% NO open circuit on the thermistor.

On the following board:

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.01-RC12 (2020-05-06b1)
Duet WiFi Server Version: 1.23

The incorrect reading can be deleted when you input the desired temp and the tool heats up normally to the requested temp.

This is with a genuine E3D thermistor cartridge.

If I revert back to an older version of DWC the issue disappears

Are you trying to use 3.2 beta with an older firmware release candidate?

Have you tried DWC 3.2 with matching firmware?

@Phaedrux

I have and still the issue persists.

Are you saying the the latest DWC is not backward compatible with older firmware ?

Phaedrux

I am not saying that, nor did I type it. The intent is backwards compatibility. I'm simply asking for the extent of conditions.

Release candidates aren't supported once a final release is out at any rate, so it's more helpful to know how it behaves on 3.1.1 or the corresponding beta release.

It does behave the same with 3.1.1 and 3.2 beta 1.

It just so happened that i'm getting it on the older firmware too hence my reason for asking if it was backward compatible after your question, which could have easily been construed (or misconstrued in this case) as there being a compatibility issue, and that is why I asked.

In your config.g do you have a G10 tool definition that sets the active and standby temps to 0?

; Tools
M563 P0 D0 H1 F0                               ; define tool 0
G10 P0 X0 Y0 Z0                                ; set tool 0 axis offsets
G10 P0 R0 S0                                   ; set initial tool 0 active and standby temperatures to 0C

I Do

And another picture to show the same issue in the latest firmware

Thanks. Can you provide your full config.g?

erm no, I'm not prepared to provide that as I fail to see the relevance, it shouldn't matter if everything works fine with an older versions of DWC, the common denominator is the newer DWC not my how my config.g is structured.

Thanks for your report.
