Best Offline CNC Controller

What is an Offline CNC Controller

CNC Offline Controller also called a stand-alone CNC controller, has the functions of a computer and CNC motion controller
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. 

–> The following products are all solid choices. We’ve based these reviews on careful research, product comparisons, and user reviews, all to provide a comprehensive guide for buying a model that fits you best. 

Offline CNC Controller vs PC

Pros

1, Offline and convenient and intuitive, similar to the operation of the machining center
2, If you do a lot of duplicates, offline is more convenient, I used to use a notebook, and I have been charging all the time, more trouble
3, Support power-off continuous carving function
4, Offline stability, In fact, it is easier to operate than mach3

Cons

CNC Offline Controller does not support the network. This is the worst. If there are many machines, use a computer and share a disk. Everyone is going to read the knife path. It is more convenient than using a USB disk. It is fast. , the version is easy to control, and the U disk is also easy to break.
