Re: [CAD_CAM_EDM_DRO] sinusoidal movement in a stepper

Hi Aksunavi, Jon,

Isn't rotating through an arc, or rolling a circle along a line a
sinusoidal process, or something like that?

Anyway, You could plot a sin function in a spread sheet, and output the
points you need as well. These points can then easily be converted to
Gcode.

A program could also be written in 'C' or whatever to generate a set of
coordinates to rotate the stepper to. Particularly easy if no
acceleration/deceleration was needed.
