Hi Roger,
With KMotionCNC you must Halt before you can Jog about and Resume. If you Jog while halted then when Resuming you will be prompted with the options shown below on how to resume back to where the Halt stopped:
KMotionCNC also has a feature to reverse along the path while in feed hold. So you can do the following:
#1 Cycle Start
#2 Feed hold
#3 Forward/Reverse
#4 Halt
#5 Jog
#6 Resume/Cycle Start
Regards
