Best Offline CNC Controller

What is offline cnc controller

Offline cnc controller also called stand alone cnc controller,it has the functions of computer and motion control card
It can work without connecting the motion control card to the computer. It only needs to remove the old control card and connect the drive directly to the offline controller.
The two types of cnc controllers are connected in the same way, but the offline controller eliminates the need to open the computer to read the tool path and work again. The offline controller has a G- that can directly read the U disk or TF card code file, some offline cnc controllers can take over the wheel.
The advantages of the offline controller are simplicity, convenience, and reduced interference.
