ALL External drivers, on expansion board

Using DM860A external drives, which perform Perfect !! with the settings below. (double Z axis)
However the new setup with HBS57 for xy is not moving at all.

Anybody out there; who has a working M569 setup of this type of external drivers...??
Thanks for your time and help.

;EXTERNAL drivers on expansion breakout board v1.1 Drive 8 and Drive 7
;Longs Motor 2H Microstep driver DM860A, SW1 upto SW7 ON= 2.8A Peak ,400 Pulse/rev
;Nema34 4 wire

Have you tried R0 instead of R1 ? Some external drivers have enable inputs, others have disable inputs. You have the correct R parameter when the drives are free to move at power up, and lock when you first try to move them (whether they move or not).

Thanks for your reply, it's very much appreciated.

Yes I tried both also with increased numbers.
;EXTERNAL drivers on expansion breakout board v1.1 Drive 5 and Drive 6
;HBS57 Closed-Loop Driver + Nema23 23SSM6440-EC1000 , 4.0A Peak, 400 Pulse/rev, 24V DC sw1-sw7 ON,SW1 on=down edge
;Nema23 4 wire, enable+ and enable- Not connected !!
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-power= free movement
Both setting R1 or R0 lock the steppers. (so that's possitive ;-))

However homing X shows the following problem.

I checked the wiring of the stepper coils A and B, according diagram and measured.

The enable cables are both disconnected on the external drives.
i tried :
ena+ and ena- connected => red led on driver
ena+ connected not functioning no warning (same phase error!!)
ena- connected not functioning no warning (same phase error!!)

any suggestions are welcome.... (my current clossed stepper setup is still a non-moving machine ;-((

It sounds to me that you haven't used a M584 command to tell RRF that the X and Y motors uses drivers 5 and 6 instead of 0 and 1.

@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.
