Purchasing new parts for new build.

[JAZZCNC]

I Already have nema 23 motors and drivers :/ im 99% sure that they support some high voltaje. I already made the mistake that purchase a lot of stuff a few years ago, will try to make it better now and follow your advices before waste more money :/

I'd doubt they'll be more than 80Vdc drives. Which means Max voltage you'll be able to run motors is 70-75Vdc and that's not enough for large nema 34 motor. Your motors are nema 23 which for 25mm ballscrew are not strong enough. I'd also wager if bought from Ebay/china they are high inductance motors which lowers performance.

i want an stiff machine, dont want tooo much precision, but of course if more precise better.

Well if you want real stiffness and precision then dispite what's been said by Lucan07 then I suggest you forget using round rail and buy some profiled linear rails. It's ok for router but when comes to stiffness and precision it sucks compared to Profiled rails and don't let anyone tell you different.

yes i will purchase Hiwin Linear rails like the one that i draw in my bad design :)
