Arduino CNC Controller

Controller to create CNC mill using Arduino Mega and a manual Mill via USB

This APP is a controller to create a CNC Mill (Computer Numerical Control).

You can create your own CNC Mill, using a Android device tablet/mobile/PC with Android-x86, and connect it to Arduino Mega 2560 R3 board via USB Port. Arduino Mega control 3 stepper motors that move a manual mill, and finally you obtain an CNC Mill.

Theoretically you can also use Android TV Box, but must include library package USB HOST and 2 devices I've tested Android TV Box with Android version 4.0 and 4.2.2 manufacturers not included.

The Android device must have OTG USB Host port to connect to "Arduino Mega 2560 R3", and you need a USB OTG cable.

This APP is designed for a low cost tablet with Android 4.0 and must have a minimum resolution of 800x480 pixels. Works on tablets only 1 core, but really if the tablet is faster mill moving faster, so it is recommended that have 4 cores.

There is a window of "Help and documentation" within the APP that explains the process (you can also download this help in PDF format on the project website http://sourceforge.net/projects/arduinocnccontroller/files ). Has instructions on how to connect the Arduino, you can use 3 standard "Arduino Motor Shield R3" to control 3 bipolar stepper motors. There is also an example for connect 3 unipolar stepper motors using 3 standard "Arduino Motor Shield R3". And there is a third example of a design of a shield board no standard for unipolar stepper motors with it's program. There are links to CAD/CAM programs and other sites.

The APP can be run in virtual mode, only with a Android device, without being connected to any milling machine, so you can practice and understand that their operation is based.

It is noted that is a BETA version so may have errors.
