Royce, as always thanks for the help! I was all geared up on running the Gecko after the last time you was telling me about them but I come across a IAI set up with a 1600 mm x and 1200 mm y. Here is a link to what I am talking about.

They have AC servo motors built in to the end of them and wrapped around the end of the ballscrew. I have taken apart some of the smaller actuators with this type of motor to use with stepper motors and they are a pain sometimes. I was hoping to find a AC servo controller that I could just use these motors and I have found Leadshine has them. Not the MX3660 but they have ind drives. Now it is back to more confusion as I don't know a thing about the AC servo side.
On another note, the x axis has a 20mm pitch screw and the y axis is 10mm. Would this be too far out for just tapering? I have 5mm actuators for the taper machine I am building and would just need this for the taper.
Thanks again for any help!
