Gentlemen,

I am, as you know, a complete beginner in CNC. I need to read the spec sheets and think through what's required, and until I have done so I'll defer to your greater experience.

But not the least valuable aspect of DIY is that at the end you know that you know exactly how it all works. I cannot live with bits of engineering in which there is the slightest fuzziness in my mind about how it works. I just have to know, and the only way to know that you know is to do it. (And until you have, you cannot possibly teach anybody else how to do it either, which is something to be considered at the senior end of the age spectrum).

I have an utterly boring meeting to attend all tomorrow morning: but then I'm looking forward to getting stuck into some spec sheets.

Ian
