I have a licensed copy of Mach 2 installed on a computer dedicated to controlling my mill and it works fine. I would like to also install it on an office computer and run it only in an offline mode to experiment with code and simulated cutting. I don't want to install the driver because of potential conflicts with the printer and several USB/parallel port dongles on that machine. Can I install mach 2 in this way? How do I do it?
