hi all.
a couple of years ago i modified a ender 3 (big time)
i added closeloop MKServo modules, made my own motherboard that uses a teensy4.1
everyting have worked great NO issues with version 2.1.2.1

now i upgraded to 2.1.2.5 and durring printing X and Y go way! off (see image)
manual control seem to work fine.

ok i think i fixed the issue, by setting
#define MINIMUM_STEPPER_POST_DIR_DELAY 650
#define MINIMUM_STEPPER_PRE_DIR_DELAY 650
this.
with 2.1.2.1 i did not need to do this.
