Y Homing on CoreXY

The Y axis is not homing the way it should do. If the X endstop is active it doesn't home Y at all.

@cando415 May I ask what type of Voron this is and where you have your endstops?
Also whattype of endstops you have, NC microswitches?
-
Ita a voron2.4. Endstops are 2 seperated NC-switches in the top left corner.
-
OK, I have a 2.4 as well and even though mine isn't a standard setup I home it on max (300, 305) in the top right corner.
I see two things when looking quickly:
- In the homey.g you go relative +360mm and then back up by trying to go relative +5 mm if I read it correctly?
- I have a pullup on my switches

You have this in your Y homing file:
G1 H1 Y+360 F6000 ; move quickly to Y axis endstop and stop there (first pass) G1 Y5 F6000 ; go back a few mm G1 H1 Y+360 F360 ; move slowly to Y axis endstop once more (second pass)All three of those moves are in the same direction.
Based on the G1 H1 moves the G1 Y5 should be G1 Y-5.

yes. -5
@Gixxerfast
checked the Endstopcontroller, rewired it. now it works fine -
