@nhof Thank you for answering those, "for moste of us" standard things.
for me totally new, and without questioning a way to misunderstand.
so if i understand right, within "tool" (group) i can define a complete axis, like the stepper, and the mechanical end switches.

Does the Duet can handle soft-switches ??

As i look at my Duet-2, i think i have a device overdone for my purpose of use.
not negatively, i find a use for them. thinking of temperature reading of my router bits.

At first, i am not a 3D printer person, i do work wit CNC routers an lathe's for me the important tasks are
the X, Y & Z axis, steps per cm velocity in mm per minute and acceleration.

As i be growing into the Duet-2, by "trial, ask & error", i find my self in expressions i have no clue what the are
and where or how to use them.
Reading is explaining a lot, but some main things i do not understand.
sometimes it is as 1 thing has two words, and the next moment in line as they are different things.

1, motor - Drive
2, printhead motor
3 tools
3 heater (why so many)
4, extruder moves
5, bang-bang mode
6, Thermostatic control

and there are more i assume

maybe someone can and will explain, how to see those in relation ..

Yess, Yess... This is the missing brick, On this i can continiu-

As in the file:

M584 X0 Y1:3 Z2 U9 E4:5:6 P5

where X= #0 stepper
where Y= #1 & #3 stepper
where Z= #2 stepper

Where U = dummy #9
where 4,5 and 6 are E-motors

i did just now:
M584 X5 Ym6 Ys7 Z8 U9 P5
where motor 5-9 are on the expansion breakout board.
As you see, i used Ym and Ys (master and slave), and P5 to make 5 motors visible.
than i did :
M584 X5 Y6:7 Z8 U9 P5
but non is happening...

@deckingman As i said before, i only have the basic config.g file.

0_1562877003983_config.g

i have tried to give the P a value of 5, but did not see really a change.

wat do i have: (board and machine are not hookt up yet)
X-axsis, Y-axis master and Y-axis slave Z-axis A and B axis (rotation head on the Z-axis)

Those last two i will be removed and not use on this machine for now.

the machine is screw-driven and i do use a stepper expansion board because the Duet 2 is not capable to run steppers over 2A, and i use external steppers.

@danal took a wile before i understood,
My board, laying next to me, is only hooked up tu 5 volt (usb) and not jet to the machine,

so as requested...

As i played with this M-code, and no change appeared, can it be so that the board actually has to be hooked up to the machine to show the status of the machine??

@deckingman ,@bearer , I still are reading and reading, my self in to this config.g file.
i do not have yet a config other than the basic one. (and experimenting from that point)

@bearer said in Display of axis:

they should be displayed if they are configured i think.

Jea, now you speak about so, i have read somewhere about this, can't remember where..

@deckingman thank you for the lead, i will make use of your info, and pointing me to the M584 code and the P values

I do not use the Duet 2 in a 3D printer, but on my CNC machines.
The machine i offered to electronic rebuild has 6 axis. 4 for the Cartesian movements ( X, Ym & Ys and the Z axis). on the Z axis is a kind of gimbal system (A & B axis) to move the former router under an angle.
If i look at the DWC screen, I only see 3 axis X,Y & Z.
Is there a way i can visualize within DWC all of my axis?? (position and movement)
