I've been trying to find a program or online converter that can take a
non-symmetric G-Code and mirror image it to cut the opposite shape while still
running around it clockwise. There is one for Windows that can split code in
half and rotate it so that with proper fixturing a mill can be used to work on
stuff larger than its X and/or Y axes, but it does not mirror. It also can do
3D probing and map G-Code to non-planar surfaces. You'd think mirroring would
be an obvious feature to add to such a program but the author is for some
reason not interested.

Foe example what if there was a tool change? Or in the case of a 3D
printer there would be plastic in the path and the extruder would
crash. Ans does reverse means the spindle goes backwards too. I'm
still thinking about what might happen if there are more than there
axis involved.
But irregardless if it would make sense, it would not be hard to write
software that would "flip" a g-code file around so it runs bottom to
top.
Some code just don't make sense to run in reverse order. For example
in the normal case you might start the spindle spinning then do some
work then turn it off. Doing this in reverse order is nonsensical:
Turn the spindle off do some stuff then turn it on. That does not
seem useful.
