Extruder stopped in mid-air without error shown

Hi! I’ve got a problem with my extruder, my machine is creality cr-10 v2, the extruder stopped randomely in the mid-air without any error shown. I tried DUMP_TMC command and nothing shows in the terminal, also the log file.

I wait and see how the stepper stopped and found it always stopped at a certain angle(position). It shaked for one seconds (moving forward and backward for a couple of steps) and stopped.

This issue started around 3 weeks ago, after i upload 0.10.0 maybe? I tried to reinstall klipper, tune cura, change cable and stepper but none of them worked

please help me, it drives me crazy

Hello @circle_around !

Can you share those?
Else we just can roll a dice and guess…

klippy.log (2.8 MB)
Sure~! This is the complete file

Is there something like a octoprint/fluid/mainsail log?

anyone has any ideas?
