RE: [CAD_CAM_EDM_DRO] Re: steppers best?

I think the construction should take care of the steering issues, at least I
hope so. We've built other units that have run pretty darned straight, and
this course is just that, and on either linoleum or hardwood, so I shouldn't
need any directional feedback. Although, if we actually get the travel
distance to within a few mm, then I might have to worry about off line error
being the major contributor. But then we could iterate the design and work
on fine tuning directional control.

Thnks for the input. Chuck

Any chance the route will be curved, or that the Robot might not go
straight? If so, you might need some kind of corrective feedback???????
