NVUM CNC Controller

NVUM V2 is a CNC (Computer Numerical Control) controller that can be used to control a machine tool such as a lathe or milling machine. It uses a USB port to communicate with a computer running Mach3 software, which is a popular CNC control software used for a wide range of applications. The NVUM V2 controller supports 3, 4, 5, and 6-axis configurations, which means it can control the movement of up to 6 axes on a machine tool. It also supports standard MPG (Manual Pulse Generator) input, which allows the operator to manually control the movement of the machine using a handwheel or other input device. CNC controllers NVUM V2 are used in a variety of industries, including manufacturing, prototyping, and hobbyist applications.
