RATTMMOTOR CNC GRBL Offline Controller, 3 Axis GRBL DIY CNC Router Offline Control Button/Module LCD Screen for Mini CNC Carving Milling Engraver Machine

Arrived extremely fast. Exactly as described.

Works well for jogging. But if a problem arises during the engraving it is almost impossible to pick up where you left off.

Fantastic for its price, makes zeroing your access on your piece quicker. No more back and forth to the machine in the monitor when starting your piece. The memory cards a cute touch but I like to watch different stats and things when I run my projects and my computer's in the same room so I have yet to use it to send my own G-Code. I dig try one of the test codes that came on it already and it worked fine.

The screen is very small and difficult to read. It is like trying to read a postage stamp for the commands. Also, controls are less intuitive than other controllers. Recommend spending a little extra and get the CNC controller that is larger and more intuitive.

This controller was able to move the XYZ axis in four selectable steps 0.1, 1.0, 5.0, and 10.0Beyond that, it WOULD NOT even machine designs that were INCLUDED on the memory card.DO NOT waste your money on this controller!

Seems okay but these never last that long.

Works as advertised. On my CNC, when it is plugged in, I cannot control the grbl via USB. At this point I never use it because controlling the CNC from laptop is much more convenient. You might consider buying it if you are in high-volume manufacturing, or if you have just one laptop and you want to walk around with it while CNC is working.

As you can see in the photo all I got was a a cable and a plastic housing that’s not shown in the product photos. By the included cable it looks like it would not have worked anyway as mine had less pins on my board.
