Re: [CAD_CAM_EDM_DRO] cnc mill project

Just a thought but I would have thought steppers would be cheaper to use on
something as small as a Taig Micromill, they are certainly powerful enough
and cnc control software and suitable interfaces are readily available on
both sides of "The Pond".

> First, thanks for the info regarding Gecko drives, I found it very useful.
My friend and I are industrial engineers at U of I and are converting a
manual Taig micromill to CNC as part of an independent study in adaptive
control systems. We currently in the very beginning stages of the project
and are trying to figure out what components to purchase for the initial
conversion. I have a pretty broad background in machine tool systems, in
addition to being a metalsmith, but I don't know all that much about CNC
interfacing. We'd like the machine to be both accurate and cheap. We've
decided to use the Gecko drivers for the project, as I've seen them on
numerous websites and all have spoken very highly about them. I was
wondering if anyone has suggestions for the type of servos we should use,
particularly: typical ranges for continuous torque, speed, voltage, and
encoder resolution (we plan on using rotary encoders). We're also interested
on upper bounds of the same parameters (i.e
> . the maximum values that are worth paying for). If anyone knows of a
cheap surplus servo supplier we'd be interested in that too Thanks a lot.
