[3.4.0b7] Firmware update changes 1LC temp

[Gixxerfast]

@dc42 Oh, mine is working fine with the v1.1 toolboard with a generic pt1000 and b7. I'm just butting in because it's interesting as I have the same setup and it's working fine ...

[Fumble]

@dc42 I notice Alex-cr is running SBC+6HC+1LC as am I while Gixxerfast is Mini5

[Alex.cr]

@dc42 said in [3.4.0b7] Firmware update changes 1LC temp:

please can you try connecting the thermistor or PT1000 to temp1 on the tool board, change config.g appropriately, and see whether the problem persists.

@dc42 I have confirmed that moving the PT1000 to temp1 did not resolve the issue. The problem persists.

[Alex.cr]

@dc42
Additional issues are occurring now. Once I performed a new heater tuning on this extruder to test the new algorithm I cannot get the heater to turn on.

The M303 completed correctly and I updated my M307 command in my config. Now when I use DWC, G10,M568, or M109/M104 commands the heater will just sit there and not heat.

Sending an M105 command confirms that the temps were requested.
If I send the appropriate M303 command the system will heat/tune and act correctly. Reuploading B6 to the 1LC restores the ability to use the heater.

I can confirm the erratic temperature reading after upgrading to B7 with 1LC v1.1. SBC + 6HC + 1LC. Flashing back to B6 returns thermistor readings to normal. Slice Engineering Hight Temp thermistor (450C).

@dc42 same here. Dyze 450€ thermistor temp0 on toolboard. Reports open circuit after upgrade

[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]

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 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.

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