@Rushmere3D
thank´s that solved my problem. Sry for bothering you.

Hello together,

i`m a new Duet/Reprap User and new to this forum. I´m currently facing a strange problem: if i want to extrude filament my x and y axis moves (corexy machine) and not the extruder-stepper. Anythin else works fine. I´m sure that there is a super simple solution for my problem but after reading anything i found in the wiki and in this forum i wasn´t able to find it.
Here is my config.g:

; Configuration file for Duet WiFi (firmware version 3)
