Something that you miss completely Jazz, is that for some people, the idea of building a CNC from scratch, and from bits and pieces lying around, and testing different methods etc. is just as much (sometimes more) enjoyable, than using the thing afterwards.

When it came to my Z , for instance, I had an old bed side that I had kept (would come in handy one day :) )


My Z works perfectly (cutting wood) , and is driven by allthread and a couple of standard nuts, with rails made from that bit of bed, and some skate bearings.

Also, some people want to cut steel, others are happy cutting foam - completely different design philosophy for both !

That's why I called my build "Scrap heap challenge" it's fun - and can be very accurate.
