Sorry if I'm way off here. A noob getting confused by this topic. The documentation for G33 <http://linuxcnc.org/docs/html/gcode_main.html#sec:G33,-G33.1:-Spindle-Synch ronized> says it move an axis based on spindle synchronised motion, so it needs K, to know how far to move on each revolution of the spindle. F will be determined by the spindle RPM.
