This is the first in a series of videos about setting up my latest and hopefully final CNC controller – using the Duet 2 Wifi / Duex 5 with RepRap firmware 3+. In this video I introduce much of what I want to do or achieve, and compare that with the previous one. I also installed a 24v two channel relay module which I’ll use for dust extraction, showing how I wiring it up and explain the code I wrote in the config.g file.
