Thermocouple M308: string too long 3.3 beta
-
Hi,
I have a Duet 6hc motherboard, and a thermocouple connected to the thermocouple daughterboard V1.1
Firmware Name: RepRapFirmware for Duet 3 MB6HC
Firmware Electronics: Duet 3 MB6HC v0.6 or 1.0
Firmware Version: 3.3beta2 (2021-03-10)
WiFi Server Version: n/a
Web Interface Version: 1.22.6the output for bedtemp is always 2000°C

This is what I get from the config tool for a thermocouple. Try this.

Are you really using 1.22.6? Using the old DWC with RRF3 can be unpredictable sometimes. Best to keep in sync with the firmware releases. Which at the moment is 3.3 beta3 for both firmware and DWC.

@phaedrux
When I install FW 3.2.2 , it works fine.
seem like a bug in FW3.3beta2 and 3.3beta3 (both give the same error back) -
Did you try the shorter line I posted in both?
The T"K" wouldn't be required because K is the default.
I'll let DC42 know that something has changed in 3.3 beta for the line length.

The strong too long should be fixed in 3.3 RC1.
