    I can not find in posts if sb mentioned it earlier but I think that from Germany this is the best thing he could buy http://www.ebay.es/itm/CNC-Set-20x-1...53.m1438.l2649

    Ok, Not Hiwin. But Cheap, in Germany and supported square rail.

    thx for the link very interesting
    I have changed the design of the machine a bit
    Everything will be made out of 80x80x4 mm thick steel
    My gantry way's about 50 KG of steel.
    I think the supported rails way about 6.6kg and the Z AX about 10 kg .
    So in total ist about 66.6 kg but maybe take 80 kg just to be sure.

    can i use these motors with a r&p system?
    i was thinking going the mechmate way : they hold the pinion against the rail with a spring.

    You could move 60-70 gantry with 2x 3nm nema 23 motor driven at 70VDC, as most people on forum do.

    The motor you show is nema 34, will have more inertia. Ok, looking at the inductance of it its not too bad, i could say its even good. But you will need to drive it at least 110VDC as per its chart, or even better use 230V main power drives, which are much more expensive than AM822.

    for software i would like to use estlcam ist a cad and machine sofware together and very easy in use.

    is there a set of nema 23 that u reccomend or do's it not really matter only that they need to be 3nm?

    What about this set?

    this is the short motor. You need the longer Nema 23 . Could buy it from Uk, Price is good and they have full kit with drives, https://www.cnc4you.co.uk/Stepper-Mo...YGH301B-Nema23

    it could but is not the ideal. I pointed you the previous message to the ideal. Building the CNc you can make like 500 mistakes. When you are not sure which, what why, just follow the recommendations :-) or look more carefully into the data. And when you dont know what it means, follow the ...

    AM882 are a good choice for the drivers. With 68V power supply.
    Why would you want to use arduino uno to run a router?
    Any software will work with the drivers.

    Got the steel since friday i was a lot and very heavy.
    this weekeind i started to weld everything together with a small inverter and it works very well.
    Just a question do i need to bolt the machine to the floor ? do i need to put rubber between the bottom of the legs and the floor to have the less vibrations?
