[BUG] Marlin 2.1.3 Beta 1 - MKS Robin Mini (Kingroon KP3) Z stepper motor moves with strong vibration and loud noise, but works normally with earlier version 2.0.9.1

[Hokeric]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

Z motor not moving as expected. Upon homing, after X and Y have homed, Z moves very slowly and with shaking loud noise even with the default motor strength 800.

I tried to increase Z motor strength to 1000 and performed move Z axis from LCD control, but it did not move. I then increased motor strength to 1200 and then moved Z axis by 10mm via LCD control, it appeared to move correctly. However, after I stored the configuration, the Z motor began to make loud noise again.

I tested the printer with older version 2.0.9.1 and it worked normally. Therefore, it is not hardware issue.

Bug Timeline

New bug. This bug is observed in 2.1.3 beta 1, as well as in 2.1.2.5

Expected behavior

Z motor should home normally, but it does not.

Actual behavior

Z motor not moving as expected. Upon homing, after X and Y have homed, Z begins to move but with strong vibration and loud noise.

Steps to Reproduce

1. Perform a homing action.

Have you tried any other versions between 2.0.9.1 & 2.1.2.5?

[Hokeric]

I tried 2.0.9.7 but was unable to compile. It said "include path error".
Since 2.0.9.1 works correctly, something might have changed between 2.0.9.1 and 2.1.2.5. Will this be traceable?

[ellensp]

2.0.9.1 is from Jun 28, 2021 and 2.1.2.5 is a few selected patches off of 2.1.2.1 dated May 17, 2023, that's 2 years of code changes to go through.

[ellensp]

you need to try a few versions in between

2.0.9.1
2.0.9.2
2.0.9.3
2.0.9.4
2.0.9.5
2.0.9.6
2.0.9.7
2.0.9.8
2.1
2.1.0.1
2.1.0.2
2.1.1
2.1.1.1
2.1.1.2
2.1.2
2.1.2.1

I tried 2.0.9.7 and 2.1.0.1, but was unable to compile. Could this be compatibility issue with VS Code? I do wish to find out since which version it has the problem.

[Hokeric]

This is the compilation error while compiling 2.1.0.1

[ellensp]

The error say there is TEMP_SENSOR_IS_MAX_TC in your Configuration.h file

But TEMP_SENSOR_IS_MAX_TC is not in the 2.1 Configuration.h file https://github.com/MarlinFirmware/Configurations/blob/2.1/config/examples/Kingroon/KP3/Configuration.h

It is however in 2.1.1 https://github.com/MarlinFirmware/Configurations/blob/2.1.1/config/examples/Kingroon/KP3/Configuration.h
but this is the wrong Configuration file

[ellensp]

change ini/stm32f1.ini line 281 https://github.com/MarlinFirmware/Marlin/blob/2.1/ini/stm32f1.ini#L281

"-DMCU_STM32F103VE -DTIMER_TONE=TIM3 -DTIMER_SERVO=TIM2"
to
"-DMCU_STM32F103VE -DTIMER_TONE=TIM3 -DTIMER_SERVO=TIM1"

[ellensp]

same error as 2.1

Was able to compile 2.0.9.7 after the .ini file change, but Z motor has the same problem.
Tried to test with 2.0.9.2, but had compilation error, as follows:

[Hokeric]

I here give summary of test results of various versions:

2.0.9.1 no problem
2.0.9.2 unable to compile, compilation error as show in response above
2.0.9.3 unable to compile, same error as above
2.0.9.4 able to compile, printer keeps self-rebooting, unable to test
2.0.9.5 has the same Z motor problem same as reported for 2.1.2.5 and 2.3.1-b1
2.0.9.6
2.0.9.7 has the same Z motor problem same as reported for 2.1.2.5 and 2.3.1-b1
2.0.9.8
2.1
2.1.0.1 printer keeps self-rebooting many times before settling down. Z motor doesn't move with motor strength 800. Increased motor strength to 1000 then Z motor can move but with loud and vibrating noise. Similar observation as the reported Z motor problem in 2.1.2.5 and 2.3.1-b1
2.1.0.2
2.1.1
2.1.1.1
2.1.1.2
2.1.2
2.1.2.1

From the above, it can be reasonably deduced that the Z motor problem began from 2.0.9.2 to 2.0.9.5.
I 'll be happy to also test 2.0.9.2 and 2.0.9.3 if the compilation error can be solved.

I have narrowed down the troubleshooting to the extent that I can.
Is there any other input that I can provide to help troubleshooting at your side?
Thank you.
