Thanks, you made my day.

I was shure it was a newbie mistake.
I have changed

M667 S0

now it is working as expected

The Maschine is a big xy System.

I have 2 Motors that drive the y axis. gantry drive
I have 2 Independent x axis on one bridge using 2 Motors ( dual x drive )
I have 4 z Motors

M574 my fault. Have changed it

M208 Reports
Axis limits - X: 0.0 min, 230.0 max, Y: 0.0 min, 450.0 max, Z: -0.2 min, 200.0 max, U: 0.0 min, 450.0 max

Having the axis combined y+10 from the web Interface runs both axis in pos. direction.
pressing u+10 runs the U axis negativ.

Many thanks for your help.

Still I probably did not understand it.

I have changed this

M584 Y3:4 Z5:6:7:8

to that

M584 Y3 U4 ; this should define the U axis
M574 U1 ; set the endstop, old endstop command was wrong
M584 Y3:4 Z5:6:7:8 ; Assign both axis to Y, Z Axis not used by now
; do all the other stuff as before

Well it is still the same.

Y axis is running parallel when M584 Y3:4 is send
U axis runs in the wrong direction when I send M584 Y3 U4

Thank you.

I tried to figure out what it is, but failed.

I updated the firmware to the latest beta, just to be shure to not running on an older Problem.
Behaves the same.

I used different drives. The last I used were 3 and 4. It is always the same.
when I separate the axis by M584 Y3 U4, the U Axis runs in the wrong direction.
While combined with M584 Y3:4 they are running in parallel.

Why did I separate the axis ?
I found an example on this Forum how to sync two axis.
I can problably invert the U axis in the macro that does the sync ( have not tried by now ), but this
does not feel right.

Well thanks for this quick Support.

I have changed the command to M584 Y1:2 Z6:7:8:9

When I do ( drive 1 and 2 combined )
G91
G1 Y10

Drive 1 will go positiv and 2 will go negativ.

Now I do
M584 Y1 U2

When I do
G91
G1 Y10 U10

both axis will go positiv direction.
Is this as expected ?

I am in construction of a new maschine. The unit has two Y axis and 4 Z Axis.
I am using Duet Ethernet and Duex5 with Firmware 1.9.2 Web Interface 1.9.3.

Now I am testing just the Y Axis

I have defined the axis like this

; Axis and motor configuration
M569 P0 S1 ; Drive 0 goes forwards
M569 P1 S1 ; Drive 1 goes forwards
M569 P2 S1 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S1 ; Drive 4 goes forwards
M569 P5 S1 ; Drive 5 goes forwards
M569 P6 S1 ; Drive 6 goes forwards
M569 P7 S1 ; Drive 7 goes forwards

;*** The homed height is deliberately set too high in the following - you will adjust it during calibration

M566 X1200 Y1200 Z1200 U1200 E1200 ; Maximum instant speed changes mm/minute

Problem:
If I separate the axis with the M584 Y1 U2 command, I can home them individually. Everthing is fine and axis are running in
the right direction.

If I Combine them with M584 Y1:2 U2 and move the axis, the U Axis is inverted .
Means the axis are not running parallel as expected, but are running in opposite directions.

Any Ideas what I did wrong
