Honestly while I am sure there are ways to workaround that particular problem I have had many situations where a jog while paused feature would have come in very very handy. It is really something sorely missing from LinuxCNC. Hell even being able to just stop the spindle or turn off the coolant would be nice to check progress let alone being able to move tool away and inspect the work during a program. This is something that would be very useful in a multitude of operational situations. Peace
