F-Yi GRBL Controller Board 3 Axis Controller Panel for DIY CNC 3018 1610 2418

This board replaced the original one on my engraver and works good!

This was a bit of a task. I followed all instructions and even had a professional look at it. The controller itself was having issues interpreting commands. The price would have been great IF it worked properly. It was easy to install but that was negated by it's actual lack of proper function. Overall the item could have been defective but I did not want a replacement.
