EMC2 can also do this, you put "HOME_IGNORE_LIMITS = YES" in the axis
section for each
axis that will work this way. EMC2 also has a button to let you
manually jog off a limit switch.
If you have separate limit inputs for each direction, it will only let
you jog in the proper direction
to get off that switch. There also is a feature to home all axes in a
specific sequence, but I don't
know how to do that one myself. I just do them one at a time.
