You could save yourself a lot of money and time if you buy this but how much it would cost to Germany I'm not sure.

I see an almost finished gantry when I look at this

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.





the machine is still in design fase so i can change a lot so if u guy's have more advice let me know

thx

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

could this one work ?
