Arduino Gcode Interpreter for MiniCNC with Z Axis

thingiverse

A basic gcode interpreter with x, y, and z axis capabilities for use with ReplicatorG can be utilized. It expands on the existing 2-D gcode interpreter by Oliv4945. Instructions This simple g-code interpreter implements the G00, G01, and M114 commands - enough to draw with a marker, including pen lifts, using output from a text to g-code program. Setup for the serial replies from an arduino is done in a basic reprap format to allow ReplicatorG to send the g-codes. This requires that the xml file be copied to the machines folder in the replicatorG directory and tinyCNC be selected as the machine type in the machine menu. Additional Notes: The interpreter does not remember previous commands - only X, Y, and Z values are stored. A line of X,Y, and/or Z values requires an associated command. However, it should correctly handle multiple commands on a single line. A defined backlash value of 1 degrees is included that can be easily changed. Getting clear text from a marker may require adjustment to the Z values used in the g-code. Excessive pressure greatly increases play in the mini CNC (at least version 0.29).
