The problem seems to be mach or perhaps just the people trying to set it up have not looked at how other controls work. I have 2 lathes one with a Fanuc control and one with a cheap Chinese Fanuc clone both have the tool nearest the operator. In this configuration a lot of the mach3 people have it set up so X is minus, this seems wrong. On my machines I just program a diameter say 30mm I don't program -30mm. Having the X reversed also reverses arc direction so it gets even more confusing.
If you can hand code a simple part then it is easy enough to modify the post to match but just throwing code into the machine and seeing what happens is quite a challenge if you can't manually program G code and modify posts.
