Whilst I can see that that method could help a lot of people, it would restrict peoples thinking. In a way I'd rather let people think for themselves and even post the odd wacky idea in build logs, as just occasionally you see a good design idea which we can all develop and benefit from. A generic design procedure can detract from innovation.

That may not make so much sense from an economic point of view.
Re: How about a mycncuk cnc router project?
The high level design logic tree would be a bit of work, but I don't think it would starve creativity. There's always place for macro and micro evolution in solving specific problems. The truth is that real world design and iteration is dirty and organic, it is not by wrote, which kind of backs up your point. The shock for people coming here is that they're going to have to get down and dirty rather than take the well trodden path.

(Slightly off topic)
I find it interesting that while everyone slags off the chinese machines, but clearly they can supply decent rails, bearings, spindles, ball screws, motors and extrusions...
How come no one is doing a kit of bits with decent electronics (geko's) and cables...
Maybe that's what the myCNCuk machine should be...
Re: How about a mycncuk cnc router project?
If it wasn't for Deming and TQM, the Chinese wouldn't be making decent anything, engineering wise. Bureaucratic and autocratic cultures don't easily refine the right way of doing things.
Re: How about a mycncuk cnc router project?
A Lego type approach would work for me.
Say you break the machine down into components such as;
Frame
Gantry
Linear motion (rails/bearings, rack & pinion, ball nuts, etc.)
Control Electronics (psu, safety circuit, bob, etc.)
Motion Electronics (stepper/servo motors & drivers)
Z axis
Spindle and VFD
Software (Mach3 Linux, DSP, etc.)
etc.
Then for each component various designs could be put forward and anyone wishing to build a machine could pick'n'mix the components to 'Lego' a machine together.
Re: How about a mycncuk cnc router project?
Yes I think that would be good, but you'd need to decide on standard sizes for each system component so you can mix and match.
Re: How about a mycncuk cnc router project?
As someone else said, to build momentum and not be reliant on any particular members or the same old members, the design should be capable of replicating itself. So the first jobs for the newly built machine is to build parts for the next set of newbies to the forum.
It could become a right of passage into the group. And there would be a shared mass of experience to help the newbie. And we can all sit around sharing our fond memories of our first mycncuk machine....
This most likely means capability to machine aluminium parts [which is any machine, so no problem! :) ].
This thread could then become the longest ever as more and more machines get built, and the design and list of suppliers is constantly refined.
Maybe all it needs is one person to post the first design and shopping list.

How did you screw the hiwin guides to the square profile?
