Duet - Extruder not working

Hey there,

this is my setup:

Board: duet V0.8.5 + Duex V0.2a
Firmware: RepRapFirmware-1.09m-dc42
Software: Repetier Host or Pronterface

The stepper motors of X,Y,Z-axis work as expected but the Extruder Motors on the Duet (E0,E1) and Duex (E1 - E4) just don't want to move.

In the config.g file I defined 6 tools:

M563 P1 D3 ; Define tool 0 (E0)
M563 P2 D4 ; Define tool 1 (E1)
M563 P3 D5 ; Define tool 2 (E2)
M563 P4 D6 ; Define tool 3 (E3)
M563 P5 D7 ; Define tool 4 (E4)
M563 P6 D8 ; Define tool 5 (E5)

Before I try to move the extruder motor, I select a tool by sending for example:

T0;

Then I send for example:

G1 E5;

and nothing happens. Also the current supplied to the board is not changing at all.

Do I somehow have to activate the drivers or is there any restriction in the software/firmware? Do I use the "tools" wrong?


thanks a lot in advance!
