I currently use 200 steps/rev motors NEMA 23 with 3.1Nm torque using such 4030 drivers. The motors have 8 wires and I run the motors at 4.2 Amps. They give me huge power and accelerations upto 6000mm/s^2 are no problem at all here.

The driver I use is configured for 1/25 microstepping.

If I could have gone for 400 steps motors I surely would have done it.

Thanks for the comments guys. I would like to get the 400 Step stepper but it is a single shaft and would work for the X and Z axis but not the Y. I need a double shaft for the Y axis the way my design is going to be. Not sure it will be a good idea to have a 1.8 degree on one axis and .9 degree on the other.

I found a tube with (3) 6 foot ACME 1/2-10 threaded rods from my first CNC router project that I am going to use for the Z table lifting mechanism. Those should work out really well and make the table pretty stable.

Now to see if I can find some double shafted steppers that are 400 steps per rev.

Cheers,
Bill

I believe it is going to work very well. It is bigger than the chain I used for the 2x. I was barely able to get the air tube and wires in the 2x chain.
