The Ultimate CNC is very new, but is ready to go production environment. For this reason we often give you updates.
Yes! Of course. If you have some problem using the software we will be happy to help.
Sorry, it isn't open source. The reason is because we want maintenance the software for long time and it is possible only if own work is renumbered. But! if you can't pay it don't worry, there are a free version completely fully functional.
To run the program on Windows 7 you need Service Pack 1 (KB976932) and also Microsoft Visual C++ Redistributable 2015 (included when install the Ultimate CNC Installer).
