So, you have to use inverse time mode, G93, to specify the time the move is to take. The deal is if you are going to include the rotary axis in the feed velocity, the radius needs to be taken into account. G code doesn't formally specify this, so EMC would have to ASSUME that in the active coordinate plane (G17 - G19) the vector distance from zero would be the radius. That was too big an assumption for the purists, so all angular axes have no feedrate.
