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 You are so right again !!!
U redefinition works now. M669 K1 U1:--1:0:0 ;
The M584 order dependency
Shows exactly what you say.
Is there an order dependency "check" list or should one be created to prevent these stupid dependency errors I made.
Again thanks for all your help.
Duet3D features are great !!
[SOLVED!! ]
My coreXY machine is working fine.
But we would like to try a new idea.... an additional U axis.
My U axis has just 1 purpose... mirroring only the X movements of my coreXY.
(I can explain why ...but this is a long story...;-))
What I need as a quick solution is something like : M669 K1 U2:0:0:0
But the K1 option (coreXY) let me change all maxtrix definitions for X,Y, Z to all weird and impossible combinations except the newly defined U axis.
It's fixed to the default Cartesian setup U0:0:0:1. (which makes sense in 99,9% of the kinematics needed)
So I tried most of the Cartesian/CoreXY/CoreXYU/CoreXYUV combinations K0,K1,K5,K8, K11.
Maybe I missed an option, which might work? (that's the reason for this post)
Any idea of mirroring only X would be appreciated.
I tried a second X stepper definition; (This is also moved by Y , because of the corexy definition)
Since this is the firmware wishlist;
I would like to propose the M669 K666 , which is numbered this way because all matrix entries are possible.
Which can be completely ridiculous and destroy your machine.
But if you do the numbers correct...you can do creative new stuff.
Thanks for your time and help.
@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.

Have you tried R0 instead of R1
Thanks for your reply, it's very much appreciated.
Yes I tried both also with increased numbers.

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 ;-((

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

Its a around 35kg;
I just picked the highest gear ratio possible for a nema17.
Just started with your 12mm/min setting.
The 20.000 steps start working as soon as you interpolate Z128, but Z256 is better for my hearing.
I also calculated the steps/s/axis, which which should be <130K/s/axis
So when z speeds hit the limit...I lose my browser connection.
No stalling Z steppers with the working configuration in the table.
So problem solved !!
20.000 steps/mm are possible...
Thanks for all the help.
@JoergS5
The first M350 is set without interpolation.
Than M92 is set... steps/mm
For the following M350 with interpolation, the steps are recalculated.
An yes it works, calibration stays intact with Z256 or Z128 defined with interpolation if you do it this way.
