@Phaedrux thanks for your help.
i wil try this now...
stil i dont know where to go from there... i have 5 ...acctualy a lot more motors ..with optical encoders on their back is it possible to make them work and to use the encoder signal or do i have to use external drivers to have a closed loop system.
at the momnt i have the duet 2 wifi but i would buy also the duet 3 if it would ´suit better to my needs .

now after opening yat i see this

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.2 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2021-01-05<LF>ok<LF>WiFi reported error: no known networks found<LF>WiFi module is idle<LF>WiFi module is idle<LF>WiFi reported[Warning: Maximal number of bytes per line exceeded!
