Hi Bill

Great idea and i agree about the Pi2 that may be what is needed. I thought that as i had most of the bits around i would start from a known good and then go from there. I have 2 of the Pi2's on order one will be used for my octoprint server. (Think that could handle the extra CPU) and then your idea would be a good 2nd use.

At this stage i will also go for one working rather than having 2 that i have 30% working. Then i will break things and change.
