I understand about the latency issue between laptop and cnc, but I can't see myself hauling my desktop computer into the shed every time I want to use my CNC Router so I took my 'Mint laptop' to my local computer shop and the guy installed Windows 7 alongside the Mint operating system (best of both worlds).
It seems to be working OK. If there is any lag between both machines its minute. Its not that I'm going to be cutting out intricut pieces every other minute of the day. The most it will be doing is cutting out sections of acrylic for the Arduino Drawing Robot (Computerised drawing machine)
Anyway thanks for your help.
