[3.4.0b7] Firmware update changes 1LC temp

[dc42]

Thanks. Please can those of you with the problem try the following:

1. Install the modified beta7 tool board firmware from https://www.dropbox.com/sh/5ubjszy9fmlvzwu/AAAeOMGP-Yi-Gn9LZwQoPfita?dl=0.

2. Check that the temperature reading is still incorrect.

3. Send M122 B# where # is the CAN address of the tool board.

4. Send M308 S# where # is the sensor number of the thermistor or PT1000 on the tool board.

5. Post the M122 and M308 responses here.

@dc42 Hi,
for me beta7+1 fixed the issue.
(theres a small typo in your post - 3. Send M121 B#)

config.g - not changed

After installing that firmware and rebooting everything it gave the correct temperature

Checked I loaded the firmware ok as I'm not the best on linux

@dc42 I can confirm that the modified firmware also works for me

[dc42]

All, thanks for trying the new version. It's somewhat annoying to me that it works, because all I did was to add some extra M122 debug! So I'm no nearer finding the cause.

[OwenD]

@dc42
Not sure if it's related but for some reason last night I started having an issue where my Duet 2 wiFi would reboot after trying to use the input shaping plugin.
M122 showed last restart reason was something like HeatStuck (don't remember exact words)
I saw no stack errors or other obvious issues.
After several attempts reinstalling the plugin and restarting the duet2 from DWC, I did a cold restart (turned off power) and the problem disappeared.

[Marshal]

@dc42 I know that feeling

i case you are wondering.
going back to 3.4.0b7 will come up with low temperature again.

Measured H correction for port "20.temp0" is -6

[Serge]

@serge After reboot, same temp values.
It seems the hotend temp value is correct, but not the bed temp than i have to calibrate.

[dc42]

@serge which temperature input on what board is the bed thermistor input connected to?

[Serge]

@dc42 Hi, the temp input for the bed is directly on the Duet 6.
; Heaters
M308 S0 P"temp0" Y"thermistor" T100000 B3950 A"Bed" ; configure sensor 0 as thermistor on pin temp0
M950 H0 C"out1" T0

[dc42]

@serge do you get a more accurate bed temperature reading if you revert to older main board firmware?

[Marshal]

@dc42
No issue with bed thermistor here:

M308 S0 P"0.temp0" Y"thermistor" T100000 B4725 C7.06e-8

[Serge]

@dc42 Hi, no, don't get more accurate.

[Serge]

@marshal Here is the documentation from RatRig

[A Former User]

This post is deleted!

[dc42]

@serge thanks, so this is not an issue with firmware 3.4.0beta7 in particular.

Have you run temperature input calibration on input temp0 of the main board (where the bed heater is connected)?

[Serge]

@dc42 No, i don't.
Did you think i have to modify the B3950 to B4725 ?
I don't know what thermistor is for B3950.

[dc42]

@serge try running ADC calibration on that input, see https://duet3d.dozuki.com/Wiki/Calibrating_thermistor_and_PT1000_readings#Section_Semi_automatic_calibration.
