Review on Unleash Your Arduino Creativity with the Longruner Arduino Professional Mechanical LKB02 by Antoine Cash

Solid product. Make sure you are using an external 12-36 volt power supply. The blue connectors on the Grbl screen make it easy to set up. When you're ready, it's basically plug and play. For the software you need the hex code first (quick on google) and then use x-loader to flash it onto the arduino/grbl screen. You can then use the universal gcode sender to launch your files. Under $100 CNC Machine, here I am! Combined with an inexpensive XY table and a power supply, I have everything I need. This is one of the most professional gadgets I own. I mean I'm used to building with plastic parts for temporary fun projects. And it should be. Any jitter in your device will result in an error in your output. With these solid details, this will be a project I will be making lots of use of.
