I have scratched myhead some more, this is my take on the user / operator side of things . . . . (And to me this is the bottom line, although it might not produce elegant code) Jogging in joint mode would only be used in practice to move off a physical limit condition. Like a hardware switch or wh

practical consideration: When milling or turning, if I pause to do 'something' I would want to be able to retract the tool in the direction of the tool axis so no damage is done to the tool or the workpiece. Normally on a 3 axis machine joint mode = coordinatemode as far as jogging goes, so there

Unsure how to adress this: Jogging assumes free mode. during the 'jog while paused' thing I posted yesterday motion is in coordinated mode, so jogging normally wouldnt work. to make it work, I see the following options: 1. just jog in cartesian space (any obvious reason why this shouldnt be po
