Re: [CAD_CAM_EDM_DRO] Feedrate overide was Re: rotary hand encoder wheels with detent

Hi Ballendo,

A feedrate override would not be hard to implement, but getting it to
work "on the fly" may pose a problem. Faster rates mean more
deceleration, which has already been calculated before the move starts.
MaxNC simply requires one to "pause" the move, and then the feedrate can
be adjusted. Looks like that's how I'll have to do it too!
