Ok, i changed the setting to diameter and get no differences but if i turn off reverse arc option, i'm getting this in my program:

But i want to do the arc to the other side but idk how to setup this to get what i want.

I don't think its a Mach3/4 fault.

My Fanuc 18i controlled lathe shows the same problem.

What did you use to create the code.  A Fanuc 6 post processor will get you runnable code on most CAM systems.

Standard 2 axis lathes should work in diameter mode and use incremental I and K or R in G02 and G03 commands.

Try swapping out your g02's and g03's. I edited my post processor to swap the two commands and everything is working for me now. It started for me when I upgraded from mach3 to mach4.
