Marlin latest bug fix update no temp. readings from hotend.

[SamppaD78]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

Old version of Marlin 2.9.3 with dyze high temp thermistor,temp table 66 is working,temperature is detected on the hotend . Updated today to bug fix 2.0 exactly the same marlin config as 2.9.3 version but no readings from hotend thermistor at all.. Displays 0C/0C. Only after reversing to old firmware i get readings from thermistor. To be clear as this is a hi-temp thermistor TD500 the room temperature values are not stable ,this was always issue with 32bit boards and this thermistore. Hoewer thermistor is mostly stable with higher temperatures.

Bug Timeline

New issue,started after updating to bug fix 2.0

Expected behavior

Expected that firmware displays normal temperature readings from hotend

Actual behavior

After update to bugfix2.0 no reading from hotend. Room temp reading show 0C if I try to preheat hotend reading is 0C and after that thermal safety is triggered and printer is halted.
Downgrading firmware to 2.9.3 resolve this issue.

Steps to Reproduce

Update to Marlin bugfix 2.0X CONFIGURATION_ADV_H_VERSION 02010000
Use temp sensor table number 66 for DT500 dyze sensor
Compile the firmware and upload.
Reboot and check temp readings on hotend.
Observed reading is 0C on room temp value and 0C on hotend with preheating turned on
After this thermal runaway safety is triggered

Disabled futures
Junction Deviation,Linear advance,Arc future,Square wave stepping,Hybrid threshold.
Enabled futures:
Stelthchop,S curve,Classic jerk,Power loss recovery,Host command,Cancel object,PSU control,TMC debbug,Pins debbug.

Version of Marlin Firmware

Latest bugfix 2.0X

Printer model

Additional information & file uploads

Issue is within the bugfix 2.0 code. Downgrading to 2.9.3 non bugfix version of marlin resolve this problem. All config settings within firmwares 2.9.3 and bugfix are the same but update outcome is diffrend as bugfix displays no readings at all on hotend.

Many build environment options available for this controller board, what of the following did you try?

STM32F103RC_btt
STM32F103RC_btt_USB
STM32F103RE_btt
STM32F103RE_btt_USB
STM32F103RC_btt_maple
STM32F103RC_btt_USB_maple
STM32F103RE_btt_maple
STM32F103RE_btt_USB_maple

I’m wondering if there are multiple vendors trying to use this thermistor number in firmware when they should be using a different one. There’s another related issue with temps being off (but not 0): #23737

You can try reverting this change since it was made after 2.0.9.3 was tagged: #23585

Using 2.9.3 solve this issue,but it would be nice to know the reason for this as a bugfix2.0 implement solutions for other problems. So update to bugfix 2.0 would be a good idea at some point of time.

Odd. Using current bugfix
I checked type 66 on ramps, temperatures are read and changing as expected (using variable resistor)
I also checked type 66 on a BOARD_BTT_SKR_E3_DIP (same build environment STM32F103RC_btt) temperatures are read and changing as expected (using variable resistor)

I even used you Configfiles only changed
#define MOTHERBOARD BOARD_BTT_SKR_E3_DIP
#define CONTROLLER_FAN_PIN PB6
#define PS_ON_PIN PB9
As these pins are not defined on my board.

Sadly I don't have a actual BOARD_BTT_SKR_MINI_E3_V2_0 to try.

I didn’t realize OP opened multiple issues.

Yes. I don't have but skr mini e3 2.0. I tested multiple times, compiling marlin from scratch, disabling Marlin futures,and only link to get this issue is Trianglelabs Dyze DT500 temp sensor on a temp sensor table 66 with skr mini and with bugfix2.0. When testing noticed that if temp table is set to 1 on purpose for this dyze design temp sensor it will report error on screen with bugfix installed,if set to 66 no readings.. When i set same incorrect value 1 or correct value 66 with marlin 2.9.3 it reports normal temperature readings no errors regardless of settings!? Strange thing,as i would expect,error or incorrect temperature reading due to incorrect firmware temp sensor table configuration regardless of firmware version.
