It would be best to use ubuntu for this specialty software. It is true that common apps tend to be portable, one of a kind software like CNC and machine controls tend to be more selective and may be difficult to install over other platforms.
In a very general sense Mint is Ubuntu. For most people they are the same. They may not be for you.
In fact you ought to use the very exact version that the software was created for to include the exact same hardware. If they built this stuff to work on Ubuntu 9 on a Pentium then use that.
Use a test box for installation. I don't know what you have but a 50 HP electric motor throwing an arm at full speed could kill someone. You can't mess up the OS so much as you can the machine. Be sure you know how the man machine interface works and how the machine cards connect and all that.
From the linuxcnc web page it says to use ubuntuLTS and don't update. That is no network to internet at all would be my choice but for sure just the OS and nothing else and don't apply any updates.
