Hi,
I very much doubt your controller has a Mach4 plugin and therefore will not work with Mach4.
Sounds like your struggling to get it to work with Mach3 let alone getting more ambitious.
You will absolutely need to download a fresh and current copy of Mach3 and start from there.
You don't need i licence to try it and experiment, just remember that jobs longer than 500
lines of code won't complete..
If you get tired of messing around with Chinese controller then consider a US or European made one,
they work and the manufacturer will back them up.
