Ballscrew Thickness!

[AdCNC]

Roughly 7-8" the drive for the Z axis would remain the same as i have now! so looks like ill be selling 3 NEMA 23 425 oz-in steppers with 3 KL-4030 Drives rated at 3A if anyones intrested! Brand new!

Another thought was i could even go for a single NEMA 42 for the X axis and drive both of the ballscrews with a belt coupled together! what are your thoughts on this guys? the NEMA42 is rated at 2830 oz-in and can work at a max of 210v do you think this would work. ( im just trying save money as funds are abit low at the moment )

Those motors have very high inertia and high inductance, so they dont spin as fast as the 34's, also the PM2278 goes up to 220V, so you will need to get a transforma regardless because it is not advised to put 230V single phase straight in.

Another Idea. :whistling: Have you thought about fixing the ballscrew and spinning the ballnut instead?

You would reduce the amount of torque needed as the mass is reduced. I have one like this that I got from ebay.

Finally why do you need so much speed? Unless it has to return home after along cut, wont you be limited by the cutting speed anyway?

I have seen this done before, but this normally involves more money and because the motor/gearing that is associated to this type is moving with the ball nut, the moving mass is higher.
