U going to End Stop Unexpectedly

JRCL

I'm working on a custom machine that has a few additional axes outside your standard cartesian printer. When I run the print from my slicer, it starts out with a G28 command and homes correctly as setup in my "homeall.g" . However, after that the U axis will unexpectedly go to its axis limit (where the end stop is) right after successfully homing all, which I don't want, and then start the print. I'm not sure where the issue lies in the scope of my config.g, homeu.g, homeall.g, or actual g.code command file. Any help is appreciated

; config.g file
; Endstops
M574 X1 S3                                      ; configure sensorless endstop for low end on X
M574 Y1 S3                                      ; configure sensorless endstop for low end on Y
M574 U1 S1 P"e0stop"                  ; configure switch-type (e.g. microswitch) endstop for low end on U via pin estop
M574 V1 S3 					; configure sensorless endstop for low end on V

M915 V R0 F0 S40			; configure stall detection for V
