Can you post homex.g as well?

Do you mean it goes the wrong way when you home all? or home z?
Can you post the rest of your homing files?
Where are your end stops located?
Where is your 0,0 origin position?
When you home, does the head travel towards the origin?
-
I see from your files , that you are homing x to min end (G1 S1 X-395), but in your config x endstop is configured as max end (M574 X2 ....), so something is messed up here. If you answer to Phaedrux questions, then we can help better.

x axis goes the wrong way when i home all
my end stops are located bottom left corner
my origin is located bottom left corner
when i home the head travels towards origin; homeall.g

@will-baxter said in HomeZ:
G1 S1 X395 Y405 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
If your end stops and origin are located at the bottom left I would expect these values to be negative rather than positive, since you want it to move towards 0.
In your home X it moves in the negative direction, so I think that's your issue. You'd have to change the direction of the next move which pulls away from the endstop abit before going back more slowly.
Make sense?
