Describe your issue:

…Hello everyone.
Im not new to Klipper, but this time after i rebuilt my AnyCubicMegazero into Voron SW I have an issue with the Movement of Y axis. Its the opposite - And everything is printed in reverse.
I’ve tried to change “dir_pin: PB2” into “dir_pin: !PB2” it helped with direction, but after it started to home it moved to another direction of endstop and almost killed the belt. What else i need to change? Thanks.
Y and x are phisicasl endstops, Z is a pinda.

Hello @kukabati !

Leave the negation as you mentioned it and insert:

homing_positive_dir: true
#   If true, homing will cause the stepper to move in a positive
#   direction (away from zero); if false, home towards zero. It is
#   better to use the default than to specify this parameter. The
#   default is true if position_endstop is near position_max and false
#   if near position_min.

If homing_positive_dir: true homes to the wrong direction, then try homing_positive_dir: false
