@dc42 @Phaedrux
Thanks for pinpoint this to RRF2/3 syntax.
I will update to 2.05 and 2.05.1 and stick to the RFF2 syntax for the M591 command
Changing to RRF3 will be done , if we have stay another month in corona lockdown.

Thanks for the help...

stay safe everybody!

SOLVED !!!

Recap:
So to copy my X and Y movements 1:1 to a new defined U-axis.

M584 X5 Y6 Z7:8 U0 E3:4 ; set drive mapping first
M584 P3 ; Only show 3 axis (not showing U in web interface)
;Redefine CoreXY kinematics for 4th axis
M669 K1 X1:1:0:1 Y1:-1-1:0:-1 U0:0:0:0 ; CoreXY redefined Adding X movement to U-axis, Adding -Y to U-axis.
;Now U(X-Y)
;M669 K1 X"movement" by (Xmotor):(Ymotor):(Zmotor):(Umotor)..etc..

[Solved !! ]

@dc42 said in HBS57 external closed loop driver M569 config needed.:
@DC42, you are so right !
I didn't uncomment my new M584 comment I would like to use with the external drivers.
M584 X5 Y6 Z7:8 E3:4 ;!!! SET mapping to external !!!!

"working" HBS57 settings :
M569 P5 S1 R0 T6.0:6.0:6.0:6.0 ; driver 5 goes forwards, requires an active high enable, 6us min step pulse, 6us min step interval, 6us DIR setup time and 6us hold time=E3 extensionboard =Xa
M569 P6 S0 R0 T6.0:6.0:6.0:6.0 ; driver 6 goes backwards, requires an active high enable, 6us min step pulse, 6us min step interval, 6us DIR setup time and 6us hold time=E2 extensionboard =Yb
NO ENABLE wires connected!
(no smaller values tested)

R1 setting generates Red LED error on HSB57 driver.

#problem solved# Thanks.

@wydowaw said in High geared (1:100) Z ; 20.000steps/mm:

interpolate Z128, but Z256 is better for my hearing.

With the Duet Ethernet and Wifi with the TMC 2660 drivers interpolation only works when using x16 microsteps interpolated to x256. The Duet MAestro drivers will interpolate to 256 from any microstepping value.

It's typically recommended to use x16 microsteps interpolated to x256 as you get good resolution, quiet operation, and the CPU doesn't get bogged down with high step generation. It's the best of all worlds.

OK thanks ,
Case Solved !!

Problem solved; Spot on !!

The micro stepping, is the problem.
Although the high geared motors (1:100) have a large number of steps/mm
M92 X80.00 Y80.00 Z20000.00 E420.00 ; set steps per mm

The micro stepping 16 and even 32 works fine... (I thought it was impossible.
32 is even beter...I was able to crank up my Z speed from F58 to F190 before the steppers are stalling.

Thanks for the great help!!
