What R&D! If they'd done any R&D then it wouldn't be made from plywood. If you consider it worth paying for R&D, then just look at the build logs on this forum and you'll find all the information you need. I've recently posted about a machine I made, and I will upload the drawings/plans to the post very soon. No I'm not charging for it as it's all information you can get for nothing if you're prepared to spend a little time reading the forums. Charging for it would be like charging people to read this website...
Jonathan, yes, my current machine does have a lot of backlash. Unfortunately there is quite a lot of play in the whole machine so I haven't even bothered trying to dial any of it out with software.

Maybe R&D was a bad term to use. The guy that sells the kits (which are cut using the machine he sells kits of btw) has revised the design and build instructions several times. He has a dedicated forum for people building the machine and has refined the design from his customers input to make it better and more fool-proof to build. 'Support' would have been a better reason for justifying the price. With several build logs to refer to from other people building identical machines (Startseite - CNC-Holzfraese), I felt that it would be worth the cost of the kit. It's the path I followed for my existing machine and it's the support and building tips/mods from the Phlatprinter community that made the build so much more enjoyable.

Jazz, My main concern was building the machine 'square'. I know how difficult it can be to build an RC aeroplane without warps etc. I'd much rather have an accurately machined metal frame that could be bolted together rather than glued and screwed!

Anyway, thanks to all the input from you guys i'm pleased to say the Plyw**d machine is looking much less likely.

Si.
