CNC_SHIELD

The main idea behind this shield is that you can make your own functional CNC with a limited budget. If you are interested in robots, you should make your own CNC machine. There are many problems that are not obvious at first. Motors, drivers, heat, software, belts, backslash. Even if you want to buy an expensive machine, and you don't have any previous experience with CNC, it is a very good idea to make one by yourself. CNC SHIELD is 100% open hardware. It is designed with EasyEDA, and you can read the schematics, check the PCB design, learn about electronics, improve it, whatever. And the most important part with Open Hardware, we can create a community, share experiences, new ideas and fix problems. This board is 100% compatible with the popular GRBL firmware 0.9. You don't need special configurations. Plug and Play. And there is a huge community behind this project, You can be part of it! ***To build a complete CNC machine you will need:*** One Arduino Uno At least, 3 drivers for the motors (you can use the popular A4988, or the more powerful DRV8825) One bipolar stepper motor for each axis One power supply. You can reuse your PC power supply with our ATX Board. The spindle (you can use a Dremel or buy a spindle on eBay) or a laser diode. The structure (aluminum t-slots, printed parts, etc)
