You do need to change the Y homing files , but I think you may have to play to get the direction correct.
Don't forget to invert all the moves or the G1 Y5 F800 will push it into the end stop.
-
The homing direction for Y should be positive direction to the endstop at the rear.

so x moves in a negative and y in a positive -

If it moves towards +X and -Y, or towards -X and +Y, then either turn the power off and swap the X and Y motor connections, or use M584 in config.g to swap the X and Y motor drivers over.
So swap your X and Y motor plugs.

changed drives to :

G1 S2 X10 F3000x and y move to the negative. so heading x to 0 and y to 0
which is the front left side of the printer. -

x and y move to the negative.
If it moves in the -X and -Y directions, change the S parameter to S1 in the M569 P0 command. Or in your case, flip the direction on your external stepper for the P0 driver, labeled as X.
Actually that might be wrong because you've now remapped which driver X is assigned to. You're now using driver 6? Flip that one.

If the head moves diagonally in the +X and +Y directions, all is well.
Move on to the next direction move test.
When you have the X motor moving correctly, test the Y motor by sending from the console:
G91
G1 S2 Y10 F3000If the head moves diagonally in the +X and -Y directions, all is well. If it moves in the -X and +Y directions, change the S parameter in the M569 P1 command to S1.
Y+ meaning to the back
-
x pos
y neg
-
Alright, so now when you jog the print head normally, does +x go to the right and Y+ to the back?
Have you changed your homing files to move to Y positive?
-
jogging is correct
y homing needs to be reversed
-
There is also some positive move need to go minus , eg the back off the end stop move , or they will push into the back stop instead of backing off.
So like I said don't change invert all y moves. -
homeall works
homex ,and homey work
and......x y jog work in the right way -
So all you need to do now is set the Z offset ?

z always worked right
-
So Zero mm is zero mm from the bed ?
-
all thats left to get back is the bltouch settings and independant z axis for bed leveling
-
@peter247 yes z0 is Zero
after it homes to z0 it backs off 5mm
