Oh - now that's an interesting offer.

And, personally, having seen his work over the last few years - I'd take autowiz up on his offer.

With one caveat (lol)
He's a pretty liberal spender with his own money.
Lord knows what he's like with other peoples.

So just because he tells you that platimum coated linear rails with custom ground diamond bearings are the only way to go. Stick to your guns and just use conventional steel instead ;-)

But otherwise. hell yeah :-)

I'd still go corexy, as out of the four main fdm printer types - and I do own examples of all four: cartesian, delta, I3 and corexy. - corexy is hands down the best.

But unless you're in a hurry - it's a great idea !
