Ultimachine say at https://ultimachine.com/products/archim-1-0a that they intend to put RRF on the Archim, but I don't know whether they have done it yet. I suggest you ask them. They haven't been in touch with me.

reinstalled config file on sd card and works now

You may be looking for [c]M302 P1[/c], which allows cold extrusion.

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

Glad you got it working. You don't need the TBCR parameters in the M305 P1 command because they are only relevant when the sensor is a thermistor. But they won't do any harm either.

wired and working, just cut connector end wire off and plugged in on end.

ok printing best prints ever finnally, was 1600mm steps for z and i opened my old merlin folder and just copied old settings and runs great now thank you.

im using RepRapFirmware Configuration Tool, and had z endstop limit switch setting on top of page and not the z probe and thought that would cancel out z probe settings on bottom, but there was these default settings in switch colum:
Trigger height at Z axis: 2.5mm
mmTrigger height on bed: 2.5mm
mmTrigger value: 600mm
A switch is used to determine the distance between nozzle and bed
i changed all settings to 0
and now works perfect

You can just upload the zip file via the Settings/General tab of Duet Web Control. But if you are upgrading a Duet WiFi to firmware 1.19 from version 1.18.2 or earlier, read https://duet3d.com/wiki/Upgrading_to_DuetWiFiFirmware_1.19.

turned out was my step setting for E motor, the filament retraction as well as my stretch problem, instead of just retracting few mm it was retracting a foot, now with right setting just backing off pressure at end of print like sopose too, thank you everyone for replying to my petty problems but is my first week in the 3d printing world.

got working, had to switch z probe setting to switch even when had the top section in the configuration tool to switch, weird

thank you

With Arduino/RAMPS electronics, when using a simple microswitch endstop, you have a 2-pin connector that you have to plug into a 3-pin socket. If you plug the 2-pin connector into the wrong end of the 3-pin connector, you short +5V to ground. This frequently blows the 5V regulator on the Arduino. It's an example of stupid design: if users have to plug a 2-pin cable socket into a 3-pin header, a lot of them will get it the wrong way round.

I guess the original designers of the Duet (Adrian Bowyer and Tony Lock) realised how stupid this was, because they chose the pinout of the 3-pin connector such that you used the two outer pins to connect a simple microswitch - the most common type of endstop switch. So it doesn't matter which way round you connect it.

Unfortunately, this means that if you convert a printer using RAMPS or similar electronics to Duet, and you don't read any of the warnings we publish about the different endstop connections but instead connect your 2-pin endstop switch cable randomly into one end of the endstop connector on the Duet, you have a 50% chance of shorting 3.3V to ground. However, the 3.3V regulator on the Duet is tougher than the one on the Arduino, so this doesn't normally cause any permanent damage.
