Mach3 is the best that I have run across. Great support wonderful running program and will only drive you slightly mad in the process.

Have been doing test cuts with the Bob Cad and my mill getting good results and having to do some edit work on the post processor as it keeps switching to imperial when i use metric and a few other minor bugs that i am finding ways to get it smooth.

Sorry to hear about the Z going south on you hope things get back the way they need to be soon for you.
