I made this program for the sole purpose of viewing three axis CNC G-Code files on my phone. I was unable to locate a free program for viewing g-code files so I wrote my own. I added the DXF and STL capability to make it a slightly more useful program. I will probably add more features but as it is the program meets my mediate need so I thought I would share it in case someone else has the same need.

G-code is a term used to describe RS-274 files they are sometimes also referred to as gcode, g code or GCode. This program is specifically for viewing g-code for a CNC milling machine or CNC router.
