Thank you DC42!

It's works like a charm!

Thank you DC42.

I followed the "Configuring multiple independent X-carriages on a Cartesian printer" tutorial to create a new axis.

Now, I'm able to see my new U axis under "Additional Axes" section in the DWC but homing or moving U through the interface doesn't produce anything.
I guess now I should map the U axis to the extruder.
Nevertheless M563 command parameter "Xnnn" and "Ynnn" allow me only to map the X or Y axis.

How I can map the U axis to the extruder?

Thank you

Here is my config.g :

Hey everyone,

I have a cartesian printer running with a Duet3D wifi board (Firmware 1.21).
I replaced my PLA extruder with a custom serynge-pump powered by a nema 11 stepper motor (11HS18-0956S)

All I want is to be able to "home" my syringe-pump with an endstop in order to place a filled syringue

My stepper motor is linked to the E0 driver and my endstop (hall-e sensor) to the E0 endstop.

Unfortunately this gcode doesn't seem to work :
G1 S1 E-100 F360

I looked also to configuring a filament-out sensors in my config.g file following this guide :
M591 D0 P1 C3 S1
but it doesn't work when I try this in the g-code console :
G1 E-100 F360

Do you have any suggestions?

Hello eveyone,

I know the question has been asked several times.
To begin, thoses posts have been a great help and I would like to thanks all the contributors :

Powering a printer with 24V has many benefits especialy for 0.9 stepper motors but it come also with downside for running 12V heated bed and fans.
One a the solutions is to use two separate power supplies, a 12V and a 24V.

About my printer
Cartesian printer
24V Power supply
Multi-extrusion

Printer Parts

1x Duet wifi
1x Panel Due
1x Heated bed (E3D Square silicone 12V - 130W attached to an alu 210x210x3mm bed)
2x Extruder (E3D Bowden Titan extruder)
1x Hotend for dual extrusion (E3D Chimera with 2x 24V-30W heater cartridge)
1x Z-Probe (Piezo20 module)
6x Stepper motors :
-- 4x Wantai 42BYGHM809 0.9* Stepper Motors (Axis control)
-- 2x Motec MT-1703HSM168RE 0.9° Stepper Motors (Extruders)
2x Endstop (Hall-E endstop)
1x MKS Mosfet controller (to control the heated bed from the duet)
1x DC/DC converter step down (to power 12V fans from the main 24V)
3x Fans (Noctua 40x20mm : 2x for the hotend, 1x for cooling the duet)
2x PSU :
-- Meanwell PSU 24V 350W (UHP-350R-24)
-- Meanwell PSU 12V 200W (UHP-200R-12)

Can you give me a feedback on the schem bellow espesialy about :

the wiring of the 12V powering fan based on this comment :
https://forum.duet3d.com/topic/3389/12v-fans-on-24v-duet-wiring/13
“If all your fans are 12V, you should connect VOUT+ (the 12V from the regulator) to the middle pin (pin 2) of J3 (Fan Voltage Select) - DO NOT CONNECT ANYTHING to the other two pins (pins 1 and 3). Then connect your fans normally to the fan headers - they will all be 12V, whether switched or unswitched.”
the wiring of the emergency button (do I need a pull-up/down resistor?)

I hope this sketch will be a clear help to people in the same case of me

Thanks by advance for your help!
