No I'm not Kidding and the OP ask's for suggestions for Good drives and to advise he buys old Analog technology is bad advise IMO.

Like I say just because your using them and happy with them doesn't make them good. It just means you don't know any better. You've already proven this by saying you havent used Digital drives so can't possibly know the difference.

Also to claim your machine is fast as it can get and is better than any other stepper machine is just plain ridiculous when your using analog drives with 50Vdc drives. Digital drives running stepper motors with 70Vdc will blow any analog drive with motors running 45Vdc out the water on every level.
Even like for like on voltage Digital drives will make difference to both speed and smoothness.

Regards the Controller making a big difference then your correct. However this is also a area where Digital drives make a huge difference over Analog when not using good motion controller Ie: PP because they handle resonance and lower grade signals so much better.

This isn't about Digital is better just for the sake of it. The truth is, whether you care to accept it or not, is that Digital is better for several reasons and anyone who has had shity Analog drives will tell you this.
