forgive my ignorance but is it possible to invert the z information within  a code without manually altering the lines
is there some sort of routine or macro for this or am i just going to have to wait until they unlock my software licnence
in my tool path generator.....  .... im using tap extension     
please dont hit me ...im really just thick ..

What if you changed the Dir LowActive for Z in ports & pins?
