Hi Guys,

I don't seem to be getting a lot of love here but hopefully you can confirm or suggest something better regarding my findings.

I have emailed around for quotes and had a couple of suggestions.

The one I am inclined to go for at the moment is the following:

On the X and Y I would have 2010 ballscrews,
On the Z 2005 ballscrew,

On the X and Y I would have Nema 34 easy servo closed loop steppers with 8Nm holding torque(3 phase)
On the Z I would have Nema 34 easy servo closed loop steppers with 4Nm holding torque

For drivers I had the following recommended:

And the following Motion controller:

The motors would be installed in direct drive and I was given the following results:

On the X for one stepper the Maximum Thrust would be 3200N (325KG) At 900 RPM (9M/Min). There are two motors on the X so the thrust value should double.

Please let me know what do you think of the above configuration and some suggestions would be welcome.

Also if you have some tips of where to introduce some savings please don't hold it in :)

Thanks,
Vass
