G540 and Mach3 set up

[OCNC]

You can reverse the axis in Mach 3. I don't have Mach in front of me right now but I think it's in the Ports and Pins screen. There should be an option (check box) to Reverse Axis.

I had a look but could not find where to reverse axis. I have installed the current version of mach3 also and now files have some added/unwanted circles? I did not draw these circle and it as if they are added to all my saved files. Is this becuase of the newer version of mach3.
I have got about 50 to a 100 saved coral files that i used cut2d to make my Gcodes. This all worked fine until i changed over from xylotex to G540 and updated to the current mach3 version.

You should find it under Config - Homing/Limits

Changed direct low in motor outputs and it has fixed problem. This has reversed the axis. I now have my original files cut the same as before.
The unwanted circle was fixed by changing a setting in config.
