Re: [CAD_CAM_EDM_DRO] Polar Coordinate based CNC

Hi Lee,

Sounds like this would be similar to a Rho-Theta arm. Yes, the
controller would have to know how to convert rectangular to polar
coordinates. I'm wondering if EMC can already do this? That would be
WILD machine!

The big benefit to me would be that the single most expensive component of a router/plama type of system is the slides and drive components (the screws or rack/pinon not the motor itself) for the longest axis (for systems of the size/type I have in mind this would be to move a gantry). But I assume that would mandate a change to the controller so it could interpret g-codes as polar coordinates. Are there any controller packages out there currently that support polar-coordinates?
