Hi Kirk: thanks for ur feed back on servo amps. I would like to take ur suggestion, but. I looked at those amps and they require an enterface board, I think. The problem is that I am short of money for this hobby and I have to improve my z axis. the stepper i have on my cnc won't move the z axis with reliability. By buying step and direction amps i can add one servo and amp, at a time and get the benefit of encoder accuracy too, without changing all axis at once. Am i wrong in thinking that? I have several computers I can choose from for this system. The high speed machine u referenced, were u talking about the computer, or an interface card. As u can see, i don't know anything about servo systems. If there is anyway u can see for me to do what u suggest, without adding another $100 or more, please let me know! Again, happy turkey day!
