external drive a4988 duet no work

dpsslaser2020

There is an external drive a4988 driver 16 steps duet3d (E2 = driver5) connected to sep, dir, enable correctly!
Physical base exruder E0 = driver3 this moves tmc2660!
I want to synchronize the two motors E0 and E2!
This config does not move E2!

does not work if I order an exruder shaft E2
"M584 X0 Y1: 4 Z2 E3: 5"!
If I set E2 "a4988" on these axes
working on E2
M584 X0:5 Y1: 4 Z2 E3
working on E2
M584 X0 Y1: 4:5 Z2 E3

yes
dual motor y axis!

what i want now is an extruder with two motors you need to have a synchronous move!

Where do you have the external driver connected?

E2 Axis assignment xyz working!
But E2 does not work on the "E" axis!

If I set E2 "a4988" on these axes
working on E2
M584 X0:5 Y1: 4 Z2 E3
working on E2
M584 X0 Y1: 4:5 Z2 E3
working on E2

You'll need to set the values for the second E drive.

Example: M350 X16 Y16 Z16 E16:16 I1

Note the E16:16

Extruders are independent axis and need to be each defined.

@dpsslaser2020 you've also only mapped your first extruder to your tool T0 (the D parameter in M563). From your config

; Tools
M563 P0 D0 H1 ; Define tool 0

You either need to define a second tool, or assign both extruders to tool T0. You can then set a 1:1 mixing ratio so that they both move the same amount (or any ratio you choose)

Auxiliary configuration for all dual motors with this setting?
but that doesn't help either!

there is a mix icon but only one engine goes for both of them to move in mix mode! alt text

E2 connection pin are correct because it works on xyz axes when I set it up!
software setup problem is in this looking for the right way!

M563 P0 D0:1 H1 F0 ; define tool 0

M567 P5 E3:5

Here you have assigned two tools. One uses extruders 0 & 1 (okay), the other tool uses extruder 1 & 2 (which doesn't exist).

In your M567 you have assigned a mixing ratio of 3:5 on tool 5 (which doesn't exist!).

You want:

M563 P0 D0:1 H1 F0 ; define tool 0 using extruder 0 and 1
M567 P0 E1:1 ; assign 1:1 mixing ratio to tool 0

It starts in a proven basic mix mode with the control E axis and both motors move in sync!
Thank you!
