[3.4.0b7] Firmware update changes 1LC temp

jay_s_uk

@alex-cr I am also getting this on one toolboard.
3.4b6 reports the normal room temperature. 3.4b7 reports -4.6 degrees.
going back to 3.4b6 on the toolboard fixes the issue

@gixxerfast

Yup can confirm.

Duet TOOL1LC rev 1.1 or later firmware version 3.4.0beta7 (2021-12-16 12:25:01)

@jay_s_uk
Thanks for confirming.

Gixxerfast

@alex-cr Do you have a thermistor or a pt1000 or something else?

Alex.cr

@gixxerfast
PT1000 in my extruder on the 1LC.

There are two thermistors for my heat bed on the 6HC. There is also a thermistor as one of my chamber sensors on the 3HC. These were unaffected.

Gixxerfast

@alex-cr So strange, I have a pt1000 as well. Wonder what this problem can be caused by.

Alex.cr

@gixxerfast

Not sure but I remember this happening during another beta. It may have been in the 3.3 beta series.

I’m running one V1.0 toolboard and one V1.1, both with thermistors

M308 S2 P"020.temp0" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 2 as thermistor on pin 121.temp0
M308 S3 P"021.temp0" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 3 as thermistor on pin 121.temp0

On the upgrade to b7 from b6 the first toolboard immediately threw a fault saying the circuit was open circuit showing the temp as -273.1

M122 also claimed the board didn’t have an accelerometer

Reflashing that board to b6 it shows within a degree of the other board at room temp.

But still no accelerometer

Gixxerfast

@fumble Just to clarify. When downgrading the toolboard to b6 you do so with the main board as well and vice versa?

@Alex-cr @Fumble @Gixxerfast @jay_s_uk 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. This will help me identify the cause.

Fumble

@dc42 Yes same using temp1 reports 18.5 with b6 and open circuit with b7

Fumble

@gixxerfast Downgrading I only updated the one toolboard. While I realise it might not be able to collect data using different firmware versions, I would have expected M122 to detect it ok

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

@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.

@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).

PCR

@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:

Install the modified beta7 tool board firmware from https://www.dropbox.com/sh/5ubjszy9fmlvzwu/AAAeOMGP-Yi-Gn9LZwQoPfita?dl=0.
Check that the temperature reading is still incorrect.
Send M122 B# where # is the CAN address of the tool board.
Send M308 S# where # is the sensor number of the thermistor or PT1000 on the tool board.
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
