Hi Jim, I think you'll need to set some values for the E axis in these commands.

M350 X16 Y16 Z16 E16 I1            ; configure microstepping with interpolation
M92 X53.33 Y53.33 Z53.33 E400     ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E2000   ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E6000; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E3000   ; set accelerations (mm/s^2)
M906 X800 Y800 Z800 E800 I30        ; set motor currents (mA) and motor idle factor in per cent

Note I just guessed at the values for steps per mm, etc etc for your extruder. You'd need to have an educated guess on what they should be.

I think its over to the config wizzards now, they're all over the forum:)

Hi Phaedrux,
Just edited config.g with your suggestions adding E400 to M92; E2000 to M566; E6000 to M203; and E3000 to M201.
No change to motor behavior. No Z motor movement. Y motors do both Y and Z commands. Some sort of motor confusion.

A Former User

Maybe roll back the dual motor drive and test each driver individually. Simplest would be to first test

M584 E0 X1 Y2 Z4 and then M584 E0 X1 Y3 Z5 and see what moves.

if you put all three lines in your config.g file you can easily select which is inactive by placing a ; in from of them.

so test Y on driver 2 + Z on driver 4

;M584 E0 X1 Y2:3 Z4:5 ; set drive mapping dual y on 2&3 + dual z on 4&5
M584 E0 X1 Y2 Z4
;M584 E0 X1 Y3 Z5

then test Y on driver 3 + Z on driver 5

;M584 E0 X1 Y2:3 Z4:5 ; set drive mapping dual y on 2&3 + dual z on 4&5
;M584 E0 X1 Y2 Z4
M584 E0 X1 Y3 Z5

and when you're ready to go back do the original

M584 E0 X1 Y2:3 Z4:5 ; set drive mapping dual y on 2&3 + dual z on 4&5
;M584 E0 X1 Y2 Z4
;M584 E0 X1 Y3 Z5

Hi Bearer, here is the setup now

M569 P4 S1                   ; physical drive 4 goes forwards
M569 P5 S1                   ; physical drive 5 goes forwards
M584 E0 X1 Y2 Z4             ; set drive mapping dual y on 2&3 + dual z on 4&5
M584 E0 X1 Y3 Z5             ; new set up 050820 date
M350 X16 Y16 Z16 I1            ; configure microstepping with interpolation
M92  X53.33 Y53.33 Z53.33 E400      ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E2000   ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E6000 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E3000    ; set accelerations (mm/s^2)

First test: This set up caused the X motor to run as expected.
Also a single Y motor moved (Not both)
And, wonderful, now a Z motor moved (not both).
I would have expected both Y motors and Z motors to move together/
Is there something I've not set right?
thanks,
Jim

Only one M584 line at the time and test the drivers do work independently.

The ideal outcome is y on driver 2 moves and z on driver 4 moves, then put in the second line and hopefully y on driver 3 and z on driver 5 will move.

then after verifying each move independently get back to trying to get both to move.

Jim46

more precisely;
X motor on Driver 1 moved +/-
Y motor on Driver 3 moved +/-
Z motor on Driver 5 moved +/-

Driver 2 & 4 no response.

Driver 2 & 4 no response.

presumably because the second M584 line overrode the first; remove or comment out the second line and verify drivers 2 and 4 work.

Jim46

M569 P5 S1                   ; physical drive 5 goes forwards
M584 E0 X1 Y2 Z4             ; set drive mapping dual y on 2&3 + dual z on 4&5
;M584 E0 X1 Y3 Z5             ; new set up 050820 date
M350 X16 Y16 Z16 I1            ; configure microstepping with interpolation

this caused:
Succcesful movements,
Y motor on Driver 2 moves +/-
Z motor on Driver 4 moves +/-

Jim46

At this point I've been able to verify successful movements of motors on:
X moves +/- on Driver 1
Y1 on Driver 2 moves +/-
Y2 on Driver 3 moves +/-
Y1 and Y2 not together
Z1 on Driver 4 moves +/-
Z2 on Driver 5 moves +/-
Z1 and Z2 not together

Can you write this and would it work?

M584 E0 X1 Y2 Y3 Z4 Z5

ah, they all worked independently then, thats good.

afaik the correct syntax was M584 E0 X1 Y2:3 Z4:5 but it could be some of the other commands require changes. Suggest you end this thread and create a new called "Independent dual X and dual Z" and post your config there to attract a config wizzard
