############ BEGIN CURA PLUGIN STAND-ALONIFICATION ############
# This part is an "adapter" to Daid's version of my original Cura/Skeinforge plugin that
# he upgraded to the lastest & simpler Cura plugin system. It enables commmand-line
# postprocessing of a gcode file, so as to insert the temperature commands at each layer.
#
# Also it is still viewed by Cura as a regular and valid plugin!
#
# To run it you need Python, then simply run it like
#   wood_standalone.py --min minTemp --max maxTemp --grain grainSize --file gcodeFile
# It will "patch" your gcode file with the appropriate M104 temperature change.
