Hi Lee,

I've been close to bringing this to your attention for a while to see if there was a way through (just in terms of giving the OP the post back I mean).

I was going to suggest seperating the thread out into "Best ways to connect to a CNC machine?" [ around post#13? ] where pros and cons of USB vs PP vs Ethernet etc. could be discussed. There are some valid discussions on that topic to be had all round I think, moderation issues aside.

Thanks
