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
working on E2
M584 X0 Y1:4 Z2:5 E3
not working on E2 don't know why?

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

@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)

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! -

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!).

Thank you!
