Re: re:microstepping speed?

---Ballendo,
thanks for the reply. I am using Maxpro step and direction software.
I find it perfect for the 2d projects I work on.
I am using a rack and pinion feed arrangement and the pinion is about
1 in dia, this gives me about .007 per step with a half step
controller. I am happy with the rapid move rate but would like to
smooth out the feed controlled moves especially for climb cutting.
Would the G201 give me a smoother feed rate without loosing too much
rapid rate?
Thanks Terry
