Ok Jazz -

This looks like more time (a lot more time) and investment than I envisaged.

I think I am going to sell everything that i have purchased!

The sad thing is - i will lose probably half of what is has cost me to date.

I have purchased the power supply, motors, extrusion, rails & screws kits and enough nuts, bolts and fittings to make 3 probably.

Oh well!!

Also, with the learning of all the different elements, i will be an old man before i master it and i am already becoming an old man!

I wanted something as an add on, that's all - it just does not seem to be worth the effort and expense of what I will get out of it.

I am actually in a very fortunate position, being more than able to purchase one, probably several, but that is not the point. (My wife gets annoyed with how much i spend in the garage)

I wanted to build it, but I don't want it to take over my life for the next several months, or years for that matter!

Even just putting all the fiddly bits together so far has taken a good few evenings!

Jazz - I do respect your comments and as an engineer as well, as I meet enough in my work to appreciate someone who knows their eggs!

Yes, i know i will get frustrated, as I have OCD (so everyone tells me) and even now, what I create is never good enough as I am soooo, so self critical.

Yes, I ask questions and challenge and may appear 'stubborn' even? Nearly as bad as you!!

Anyway, thanks for the lesson -

A man who never tried will never learn!

Thanks to you and all the rest of you for your time, effort and patience.
