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.. |

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

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. =) |
