Extrude and retract backwards.

Borgtribble

I'm running ender 3 with microswiss direct drive extruder. I believe everything is installed correctly but for some reason when using the extrude command the filament retracts and using the retract command the filament feeds into the hotend. ? It's funny but also frustrating lol.

@Borgtribble Change the S value of the M569 command for the extruder. (S0 or S1)

You likely need to change the direction of rotation of your extruder motor in the M569 S command in config.g.

@Borgtribble

Look in config.g for a line like this for your extruder driver(s)
M569 P3 S0 ; physical drive 3 (E0) goes backwards

If the S parameter is set to zero, set it to one.
If it's currently set to one, set it to zero.
Adjust the comment to the opposite direction of whatever it is now for clarity

Edit: . Too slow

like this!

; Drives
M569 P0 S0 ; physical drive 0 goes backwards
M569 P1 S0 ; physical drive 1 goes backwards
M569 P2 S1 ; physical drive 2 goes forwards
M569 P3 S0 ; physical drive 3 goes backwards

@Flynbrd
I have no reference point as you only posted one set of commands, but as long as you have the right driver number (usually 3) then yes.
