M563 P0 D0:1 H1 F0 ; define tool 0
M563 P1 D0:2 H1 F0 ; define tool 1
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!
Have a nice day!

Where do you have it connected? The expansion header?

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!

@engikeneer said in external drive a4988 duet no work:

@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)

M563 P0 D0:1 H1 F0 ; define tool 0
M563 P1 D0:2 H1 F0 ; define tool 1
M567 P5 E3:5

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

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.

but that doesn't help either!

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

yes
dual motor y axis!

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

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!
