Review on HiLetgo® Engraver Printer Expansion Arduino by Christopher Clearfield

Great product for the price, soldering could be a bit better. For the ones I received, I had to bend some of the connectors a bit to fit the stepper motor drivers. However, note that this is version 3.0 of CNC Shield, which means that it is not fully compatible with the latest version 1.1 of GRBL. The GRBL pinout for Z Limit and Spindle Enable has changed and if you want to use these features with this shield you will need to connect directly to the Arduino pins and cut 2 pins from the shield. It works great, you just have to be aware of it. Not because this product is bad, the product is good! It's just that the V3.0 screen doesn't have the new GRBL V1.1 pinout.
