change slicer (cura / slic3r)-> not change
change main board(mks gel l / skr 1.3) -> not change
change MICROSTEP_MODES(16,32,64)-> not change

G90
G1 X10 Y10 Z10
G1 X20 Y20 Z20
all movie 10mm
there is no problem with the movement distance even with only one axis

what should I do ?

I think it's not perfect but better. The other is very similar.

Definitely see the bowden tube even wiggling. I'm going to agree that the leadscrews are the culprits. Are they remountable to the stepper motor? Maybe the connections aren't straight? Otherwise try to mount them upside down, helped me out once.
