Ok thats confirms most of what I understood. Just a bit confused about BOB. https://onedrive.live.com/view.aspx?...PSeNu5hZHOhv5k seems to show a BOB but also a controller conmbined ...
.....but is that what a BOB is and I have a really cheap one on the chinese CNC box??

Andy What you have shown is just a BOB with a few whistles on it. BOB stands for break out board or in other words if you like a simple junction box. To keep things simple can you not put a PP card in you pc. You need to put some better pictures up. Have you tried to power up what you have? Are you happy playing with electrics?
