I have a full version of Mach3 and use te Plasma profile and the Reverse Run button does not work, I have tried many ways and still not working, anyone know how to fix it?

Its not something I have ever used but just tested here and it seems fine. What exactly are you doing when testing? What I did was load the roadrunner file, let it run a bit then feedhold then pressed reverse run and it did just that.

Thanks Hood, I load de roadrunner file to test and the reverse it's works!!! :O my others G-Code files works very well,but less the reverse option, looks like the problem is the software, I generate my files with Pronest, I think the problem is the post procesor of Pronest acctually is set the BurnySWA post procesor, i will open a new post for look someone help me with it.
