If you watch one vid, https://www.youtube.com/watch?v=6Qa_SN9n-MY they open an acorn_mill_plc.src file. On the lathe software, there is no such file. I can reinstall and do the Mill bit on this main PC of mine to try it. The other issue is that the board and machine is in the garage, without removing the board and bringing it inside, I cannot 'play' on my main PC in the house.

I also looked to see if we can change the IP address of the board so that I can 'lan' it. At the moment, my garage PC has only 1 NIC which means that whilst its connected to the board, I have no internet access.
