I read how the duet and archim use same processor and between my two printers i like the duet reprap firmware way better than my Archim with marlin4due. But i cant find any ware how to convert my firmware on my archim and dont want to spend another cple hundred for another duet board when my archim is basically same thing

reinstalled config file on sd card and works now

i installed new y endstop switch so i used the rrf configeration tool like i have many times before. but this time after installing new settings, i can get connected on web interface control but each time go to setting i get unconnected and this error
Communication Error

An AJAX error has been reported, so the current session has been terminated.

Please check if your printer is still on and try to connect again.

trying set up duet control features first one is to extrude 5mm filament, is there way to do it with heaters off

; Extrude 5mm filament

k working thank you

; General preferences
M111 S0 ; Debugging off
G21 ; Work in millimetres
G90 ; Send absolute coordinates…
M83 ; ...but relative extruder moves
M555 P1 ; Set firmware compatibility to look like RepRapFirmare
M208 X0 Y0 Z0 S1 ; Set axis minima
M208 X200 Y200 Z200 S0 ; Set axis maxima

G31 P600 X0 Y0 Z2.26 ; Set Z probe trigger value, offset and trigger height
M557 X15:185 Y15:185 S20 ; Define mesh grid

ya changed the z to 2.26 if that was right place

i thought somthing in hear should state that or be changed to match, or do i get rid of this file also
; homez.g
; called to home the Z axis
G91 ; relative mode
G1 Z4 F200 ; raise head 4mm to ensure it is above the Z probe trigger height
G90 ; back to absolute mode
G1 X100 Y100 F2000 ; put head over the centre of the bed, or wherever you want to probe
G30 ; lower head, stop when probe triggered and set Z to trigger height

did all of that and tested good if mean the paper test and numbers changing 400s to 500s, its working and can calabrate it and works right reading the bed and setting the g31 command.
but any time i have to rehome z it dosnt stop on time even after lights up

changed p2 to p1 and no difrance

have mosly working now exept after reboots wene have to home z the red light is flashing and reading but keeps going into bed to deep.

is it in these settings making it do that,, i want it to use x switch but on highend not low end

do i need that file, i erased this file and now tries homing in middle like directions say should
