Well another year has passed and this thing is still not up and running.....I now have all the ballscrews so time to sort the motors and mounts (grandfather clock massacre coming up )

Take 3

I need some help with the steppers. I have read a few threads and it seems that a nema 23 or 24 will be fine for this size mill and for financial reasons I'm stuck with the m542-G drivers that I got from Zapp and using a 40V supply. Hopping to direct drive a 3N motor on a 1605 ballscrew.

First question is which is the best 3 or 4N steeper at the moment?

Ive seen this one from zapp

or this one from CNC 4U

Having bought from Gary before I was going to go the 3N one but if the 4N is just as good Id rather have the extra power.


Thanks in advance
