Homing issue

Work Horse XL

So I have homing issues with a duet 3 hc6 board with firmware with current stable release 3.4.5. The machine will not home all axes at the same time. The X just says put why the U,Y,Z home. I'm not sure what's going on here.
Home.g

G91                     ; relative positioning
T0 P0                   ; Select Tool 0 before homing
G1 H2 Z5 F6000          ; lift Z relative to current position
G1 H1 X-570 Y550 U470 F4500 ; move quickly to X or Y endstop and stop there (first pass)
G1 H1 X-570            ; home X axis
G1 H1 U570             ; home X1 axis
G1 H1 Y570             ; home Y axis
G1 X5 Y-5 U-5 F6000          ; go back a few mm
G1 H1 X-20 F360        ; move slowly to X axis endstop once more (second pass)
G1 H1 Y20             ; then move slowly to Y axis endstop
G1 H1 U20             ; then move slowly to X axis endstop
G90                     ; absolute positioning
G1 X30 Y30 F6000        ; go to first bed probe point and home Z
G30                     ; home Z by probing the bed

; Uncomment the following lines to lift Z after probing
;G91                    ; relative positioning
;G1 Z5 F100             ; lift Z relative to current position
;G90                    ; absolute positioning

@Work-Horse-XL Most likely your X endstop is marked as 'at max/min stop', ie already triggered. Test the endstops are functioning correctly; see https://docs.duet3d.com/en/How_to_guides/Commissioning#h-8-check-endstops

@droftarts Thank you droftarts! You was correct about the endstops. They worked correctly but because they was inverted it was causings homing issues. I changed the wires on the endstops to I could remove the ! and now it's homing great. Thank you again.
