M584 X0 Y1:4 Z2 E3:4You've got driver 4 bound to Y and E. Which is it?
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
M584 X0 Y1:4 Z2:5 E3
not working on E2 don't know why?

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 0You 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)

Where do you have the external driver connected?

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! -

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

Thank you!
Have a nice day!
