I designed my own board but due to unavailable chippies i didnt wanna wait and bought these Duet boards.
ill upload a piccie here. Its design with in mind the Jubilee folks with 4 tools

Im running my very first testprint on this homemade printer now, is awesome feeling
thanks for the fast reply!

All of the drivers still operate normally with all NEMA17 on it. So none of the drivers is defective or burned out. my 3D printer functions, it homes all axis, it does the tramming. it just wont let the pancake motors rotate. i connected them to all of the drivers and they just dont work.
Please stop replying on the wiring because i connect the coils correctly. 1 coil on 1-2 pin other coil to 3-4 pin. i looked at the wiring schematic of the Duet board.
So nema17 just works fine, i know the wiring can be different for motors, thats exactly why i measured which pairs are the coils, to not make mistakes here.

Im completely in the dark about what can cause this. I posted the config file im using. Can someone comment on the settings for the Extruder?
I cant think of anything wrong there tbh because it has all the settings the other drivers get.
Also tried different current settings, nothing changes. tried without interpolation, etc...

I connect the pancakes to my ender3 board which runs on a SKR turbo with Marlin and there the round pancakes just work fine, rotating both directions
No worries.

If you guys dont have a clue either, then just say it. dont bring up the wiring again
Thanks anyways.

i just changed the Y and Z steps to just 1 value for each letter. Does the same goes for the current settings and others like acceleration, speed?

After getting used to reprap and DWC i would hate to change back, a lot of work again, time and money invested lost. im not happy, the printer as good as finished but without the extruder running its useless sitting there.

Aha, i copied a homez.g from cris on youtube. this doesnt contain a G30 command. That probably is the culprit.
I changed this and gonna run a test.

Thanks mate

Fixed, the absence of a G30 in homez.g was the problem.

Hi, i have a issue with the bed mesh after i set the Z height offset in config.
i run the G32 before Bed mesh probing.
When the value is Z0.0 probe offset in config, the bed mesh probing works fine. when i set the offset (aquired with the tuning procedure) in my case Z0.85 (a positive number with use of BLTouch?)
I get the warning "to large Z offset" in the console after Bed mesh probing and shows the projection of the bed in the height map about this offset under the grid.

Im using rrf 3.3

"bed.g in config file"

M561 ; clear any bed transform
G29 S2 ; clear bed height map
G28 ; home all axis
G30 P0 X70 Y10 Z-99999 ; probe near a leadscrew
G30 P1 X70 Y290 Z-99999 ; probe near a leadscrew
G30 P2 X580 Y290 Z-99999 ; probe near a leadscrew
G30 P3 X580 Y10 Z-99999 S4 ; probe near a leadscrew and calibrate 4 motors

"z probe macro"
G28 ; home all axis
G29 S0 ; Probes the bed, saves the height map and activate bed compensation
G1 X300 Y150 F3000 ; go to center bed

"config.g"

; Z-Probe
M950 S0 C"duex.pwm1" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T4000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X36 Y9 Z0.85 ; set Z probe trigger value, offset and trigger height
M557 X65:585 Y20:280 S130 ; define mesh grid

; Pressure Advance
M572 D0 S0.05 ; pressure advance typical for direct drive extruder starts at 0.025

; Taper Height - i disabled taper height just to exclude it for solving problem
;M376 H5 ; tapering off the bed mesh compensation in mm

I did the changes PCR suggested otherwise i would never have found the solution
@PCR
Thanks mate, by removing values from the config as you suggested, the odd behaviour of the software was gone and round pancake worked.

@generisi
Hi, i appreciate your help ofcourse.

Good news mate, after i removed the values from Y and Z for the other motors on that axis in the config file, so only 1 value for Y and 1 value for Z, after upload and reset the pancake extruder WORKED!!!
It has nothing to do with the wiring but appearantly the values from Y and Z in the config file did some really odd magic preventing the 36mm round pancake to rotate. It did not bother a NEMA17

I ask DC42 to try and replicate this oddly behaviour as i gues its a very interesting conflict somewhere??

So my problem is solved and im a happy camper.

@dc42 Same measurement, same wiring like other picture but just more clear in view.

Hurray the stepper is rotating!!! The only thing i changed today was that i removed the (not needed) steps per mm in the config file from the Y and Z axis. This has nothing to do with E axis right?!
BUT appearantly , how in the hell this is possible i dunno, it fucked up the pancake steppers. Im completely stunned here and i would like to ask DC42 to try and replicate this. the more values registered under Y and Z axis must have crazed the system in some kinda really odd way.
Wow unbelievable, but im so happy it works now, jeeeez im speechless.

This has no solution for the Extruder stepper problem but that aside.

Quote "RepRapFirmware does not support individual motor settings where an axis has multiple motors connected to different stepper drivers. The first parameter specified will be used for all motors on the axis. You should use identical motors on any axis that has more than one motor to avoid unexpected behaviour." end quote.

I use identical motors on my axis.
This means that my Z-axis will always run out of sync go skewed in height while the motors are not exactly the same? I had to calibrate them.
Have them raise Z 450mm then measure the actual distance and do some calculation to adjust the number of steps per mm per motor.
They didnt raise the gantry at all corners exactly accurate. Same as you do for extruding exact amount of filament.
But oddly enough, after the calibration, feed in these steps in the config, the 4 corners does run accurate so another wierd thing goin on then?

This would be 1 more reason to step away from reprap software?

@dc42
the diagram showed does not represent de motor i have. i measured the coils and the correct pairs for my motor are black/green and red/blue.
Otherwise i couldnt measure the resistance no?

So, this is not a wiring problem, i got more pancakes with different color wires. i measure the coils which are what and then connect, same problem no rotation, just a little bit of hum. when i connect a nema17 thats runs quite normal, i noticed however some hickup that it wouldnt start rotating.
I also tested the round 36mm pancakes on other drivers on the board X, Y, Z (these drive my NEMA17's. all drivers same result, no rotation.
It must be some PWM or whatever signal not quite work with the small round motors?

Further... i used same pancake motors with connector on my ender 3 board, motors run normally.
I just have no clue whats goin on here. i post my config file.

@gixxerfast
hi mate,

I just tested my 3 pancakes on my ender 3 which has a SKR board and runs marlin. pancakes run fine. no problems.

Im gonna sell my duet2 wifi duex tft, never gonna look back.
I just ordered a BTT Octopus board which has 8 drivers on it with TMC 2209's all problems sorted.
