This is quite different. It is NOT while a program is paused, but when
the servos are
shut off by going into E-stop. This will abort the running program in
any case. But, the
coordinate system alignment is maintained, you can manually (as in hand
cranks)
move the machine and then return from E-stop with the same coordinates.
Then, you would have to select the right program line to restart from.

So, this is NOT pausing, moving and then resuming the program by CNC
jogging. I really don't do this often at all. But, I do like that I
can go to
E-stop without losing the machine alignment. That is a safety issue as
well.
