@lbtqsb It's very simple.
Install the Repetier Server raspberry PI image from here: https://www.repetier-server.com/download-images/
The image include all the Duet software preinstalled.
Edit the file /boot/repetier-image-setup.txt file in the image using Putty, and modify these lines from "0" to "1":
# Newer duet boards support a connection method called SBC where all communication is done via
# SPI. It needs the DuetControlServer to control it. Set value to 1 to start the DuetControlServer
# at boot and connect via SPI. Do this only if the spi pins are not connected with anything else!
RUN_DSC=1
# Duet also provides a DuetWebServer to control the printer or install updates. We have configured
# it to run on port 3000. To activate this as well set value to 1.
RUN_DWS=1
Save it and restart the Pi.
After this setup, you can access Repetier Server frontend at http://your_ip:3344 or Duet DWC frontend at http://your_ip:3000
