# From http://www.ahha.com/VarsAndMacros.doc
# If you wish to run macros using comments in parentheses, the comment character must be changed from a semi-colon to a left parenthesis.
# Note: the original closing single quotation mark was not ascii, so I replaced it with an apostrophe.
# To do this, the following line should be placed at the beginning of the G-Code file that calls the macro:
# self.addLine( "(*CMST '('*)" ) # Gcode to convert the comment character to '('.
self.addFromUpperLowerFile( 'Start.txt' ) # Add a start file if it exists.
self.addLine( '(<creator> skeinforge May 28, 2008 )' ) # GCode formatted comment
self.addLine( 'M110' ) # GCode for compatibility with Nophead's code.
self.addLine( '(<extruderInitialization> )' ) # GCode formatted comment
self.addLine( 'G21' ) # Set units to mm.
self.addLine( 'G90' ) # Set positioning to absolute.
self.addLine( 'G28' ) # Start at home.
self.addLine( 'M103' ) # Turn extruder off.
self.addLine( 'M104 S200' ) # Set temperature to 200.
self.addLine( 'M105' ) # Custom code for temperature reading.
self.addLine( 'M108 S210' ) # Set extruder speed to 210.
self.addFromUpperLowerFile( 'EndOfTheBeginning.txt' ) # Add a second start file if it exists.
self.addLine( '(<extrusionDiameter> ' + euclidean.getRoundedToThreePlaces( self.extrusionDiameter ) + ' )' ) # Set extrusion diameter.
