NeoTech:
This is actually great reading. damn i want that book and learn german..

Here is some design iterations...
Head is redesigned, the frame is bulked up, the hangout from Z is shortened, the table is made smaller for.. well reasons..

RobWilson:
Hi Neo ,

 I can see this being a canny project to keep an eye on mate  :thumbup:  ,interesting design  :med:

NeoTech:
So i thought i should dumpsom pictures.. of stuff sourced so far.

Start with an image of the last design iteration - can be useful i guess.
And after that first out, 16 pin connectors for encoders, aviation graded, 1.5kW servo motors for driving stuff around.
Granitedevices Argon Servo drivers, these i got for a hefty discount, thank you Tero over at granite.
And lastly a 6i25 + 7i77 + 7i84 MESA card setup, i first bought a parallell kit of this and couldnt find any good info - so thats a waste of money. But this should work.

Then cabinette., Hiwin 30mm rails with heavy load carriages and heavy preload, second 32mm ballscrews with double nuts and a 5mm pitch, and lastly claw connectors as im planning to directdrive this in the first iteration..

I need to get my hands on a 5.5kW Spindle servo motor that runs 3000rpm minimum - if anyone can scrounge up one for a good price point please gimme a shout.
And im still haggling over the BT40 spindle housing and pulleys with the chinese lady.. that drive a hard bargain.

awemawson:
Who's been spending his hard earned cash then?  :ddb:

NeoTech:
Hard earned is a stretch.. most of this is chinese actually.. not the cabinette - cuz that thing weighs a ton..
The most expensive is the Argon drivers.  =)
