The "No ATC" stands for "No Automatic Tool Changer", if your machine doesn`t have a tool changer then it will need slightly different code than if it did.
If you have BobCAD 4 Axis Standard then when you install BobCAD you would be best off setting the software to the BC_4X_Mill and using the BC_4X_Mill.MillPst post processor, this PP will already be in your installation of V26, this system is Fanuc based as is Mach3, just in case you didn`t know Mach4 is now available for Hobbyists, it is way better than Mach3 so I would suggest you look into getting Mach4, one reason for that is although there is a huge amount of information about Mach3 on the ForumI have heard it is no longer supported since Mach4 was released. JFYI
Other than setting the machine limits in the software under the two "Current Settings" tabs and your personal preferences of how the software looks/feels for you and maybe a "tweak" or two to the PP.
Just shout if you need any help with the initial setting up but it is pretty easy really
Regards
Rob
