Orca and Klipper

[acheljay]

There is some things that I don't understand :

1. does pressure advance option is for Marlin or Klipper, cause when I activate it and paste my value, the print is worse than without it activated.
2. does firmware retraction is for marlin or klipper : activated and its a total failure.
3. How to put correctly the acceleration and acceleration to deceleration value (a %). I put 3300 mm/s² as in my printer.cfg and ... I have 500 mm/s² with half in acceleration to deceleration ... I have tried many things and its stuck to other values that I entered ... Is it possible to put those values to "0" to let klipper use its own value from the printer.cfg ???

If there is a Klipper flavour Gcode, does it is possible when selecting that to have the direct options for this firmware (a special tab to enter the values of klipper and remove others ... ).
