Only 2 axis is homing delta 3d printer

[chasingsun]

Hello,
I just install my duet wifi and also upgrade it to 1.19 firmware.
I tried to home all axis x,y,z and i notice there is a problem with it.

If x and y hit home first z will stop moving ==> homing failed on z
if x and z hit home first y will stop moving ==> homing failed on y
if y and z hit home first x will stop moving ==> homing failed on x

Here is my delta homing file:
G91 ; use relative positioning
G1 S1 X300 Y300 Z300 F1000 ; move all carriages up 300mm, stopping at the endstops
G1 S2 X-5 Y-5 Z-5 ; move all towers down 5mm
G1 S1 X8 Y8 Z8 F500 ; move towers slowly up 8mm, stopping at the endstops
G1 S2 X-5 Y-5 Z-5 F1000 ; move carriages down 5mm
G90

Here is my endstop section in config.g
; Endstops
M574 X2 Y2 Z2 S1 ; Define active high microswitches
M558 P1 X0 Y0 Z0 H5 F120 T6000 ; Set Z probe type to unmodulated, the axes for which it is used and the probe + travel speeds
M557 R130 S20 ; Define mesh grid

Anyone have this problem??? Thanks you!

The main G1 S1 homing command in your homedelta.g file only allows for 300mm of movement of each carriage to reach the homing switch from any initial position. I suspect that isn't enough for your printer.
