Standalone CNC machine

Hello All,

I am thinking of building a CNC machine that is standalone, no PC. This would be a small desktop machine. Looking to use the Arduino to send the gcode to a TinyG. I currently have the TinyG and works great when connected to a PC.

My thought was to use an Arduino MEGA with a USB host shield and SD card. I can use the Arduino to take input from the switches (Start, Stop, Etc.) and possibly a LCD screen. LCD screen is not required but would look nice.

I can store the gcode on the SD card, SneakerNet it to the CNC and run it.

Possible?

Suggestions?

Yes this is very possible, it should be relitave straightforward.

Very much possible, there are numerous examples online that tell you exactly what to do (and what not to do).
