What can you do with the SB 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.
SB CNC SHIELD is 100% open hardware. It is designed with KiCad, 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. You don't need special configurations. Plug and Play.

And there is a huge community behind this project, You can be part of it!

Why no a full CNC board?
Well, you can go with a complete board. If you are serious about CNC, you should do it. A complete board is autonomous. You don't need a computer to send commands to the machine.

There are some boards open source, with a good community. That is very important if you want good support. But most of them, they are closed source. Or they have a custom firmware.

For example, some integrated boards include the drivers within the board. That could be a problem. Drivers can get hot and it is not difficult to burn one. And in some cases, it is a good idea to use different drivers for each axis.

And they have a higher price. Usually more than $100. If you are making a small CNC, for casual projects, this is a big deal.

What else do I need?
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)
CNC Shield Features
Beautiful design in Black. With Gold finish, colored pin headers and a blue reset button.
Cute easy yellow jumpers!
Molex power connector rated at 15A. Cheap Chinese plastic connectors can get burned!.
You can use AWG22 cables for the power supply.
100% Compatible with the GRBL firmware. Plug and Play.
You can duplicate any axis, or sacrifice your spindle control for a 4th axis. Simply change the jumpers, and duplicate any axis.
35V Capacitors. You can use 24V power supplies without any problem.-
Endstops for X,Y,Z. You can connect the maximum and minimum limit for each axis.
Easy to Access Reset button
Configurable Emergency Button (normally open or normally closed)
You can use the PWM features in GRBL to control the spindle speed. This is a great feature for metal and wood works.
You can configure micro stepping for each driver, for a fluid movement.
External driver connector. You can use professional and expensive drivers, like the Gecko drivers.
You can use the extended pins from GRBL, like Coolant, Pause/Hold, Resume, and Abort
UART connectors. You can use a Bluetooth adapter for a wireless CNC machine.
i2c connection. You can use a temperature sensor for example (but you have to modify the GRBL source code)
