You should be able to add a global override to the flow percentage on Marlin firmware printers.

In step based motion control, the time between two steps is calculated directly from velocity. If that time is not constant then you are accelerating or decelerating based on a specified acceleration. The next time between steps is calculated from the current velocity based on the desired acceleration. However when moving 2 or 3 axes at once, this can result ...

It seems the pinout scheme changed on the Creality board between the versions V4.2.2 and 4.2.8. For example, PB9 & PC2 were inverted between step_pin and dir_pin.

[stepper_x]
step_pin: PB9
dir_pin: PC2
enable_pin: !PC3
step_distance: .0125
endstop_pin: ^PA5
