@Chriss thank you that is helping i messed up with the M569 im working on that now.

@jay_s_uk yes i have i pre generated the config from the configuration tool

im working on a corexy printer and i need to home first the Y axis and then the X

for doing the home of Y i need to move the X a little bit to clear some space for the X switch
my homey.g looks like this:

; homey.g
; called to home the Y axis
;

; lift Z
G91 ; relative positioning
G1 H2 Z5 ; move Z relative to current position to avoid dragging nozzle over the bed
G90 ;absolute positioning

; home Y
G1 H2 X15 F2500
G1 H1 Y-450 F2500 ; coarse home in the -Y direction
G1 Y10 F3000 ; move back 5mm
G1 H1 Y-15 F300 ; fine home in the -Y direction
G1 H2 Z-5 F6000 ; lower Z again

the first issue i have is when i do the G1 H2 X15 F2500 the gantry moves in a diagonal instead of only X, the rest of the process is ok and the homing works fine

and when the big problems start is the homex.g that looks like this:

; homex.g
; called to home the X axis
;

; lift Z
G91 ; relative positioning
G1 H2 Z5 ; move Z relative to current position to avoid dragging nozzle over the bed
G90 ; absolute positioning

; home X
G1 H2 X15 F6000
G1 H1 X-450 F2600 ; coarse home in the -X direction
G1 X10 F6000 ; move back 5mm
G1 H1 X-15 F500 ; fine home in the -X direction
G1 H2 Z-5 F6000 ; lower Z again

the first move when run homex.g moves the y axis away so the rest of the process fails

both of the endstop switches are static and the gantry moves to them in both axis

where is my gcode failing?

i re generated all configs and nothing changed
i keep searching for the issue and find that some motors have they coils inverted
almost all my motors have that and none of my cables is inverted to work like that
so start changing cables and find that works

i have a clone duet2 i bought it in 2019 used for 3 years and needed to move and disarmed the printed and was in a box for 2 years now
i started working on it again and the first thing i do was to update it to 3.5 firmware version and that worked fine
now when i try to move the motors the motors vibrate but not move
im testing only with the motors without load and this very minimal config

i tried diferent cables diferent motors in diferent drivers even diferent motors and nothing
any ideas?
