Comb is a script to comb the extrusion hair of a gcode file.
The default 'Activate Comb' checkbox is on. When it is on, the functions described below will work, when it is off, the functions
will not be called.
Comb bends the extruder travel paths around holes in the slice, to avoid stringers. It moves the extruder to the inside of outer
perimeters before turning the extruder on so any start up ooze will be inside the shape. It jitters the loop end position to a
different place on each layer to prevent the a ridge from forming. The 'Arrival Inset Follow Distance over Extrusion Width' is the
ratio of the amount before the start of the outer perimeter the extruder will be moved to. A high value means the extruder will
move way before the beginning of the perimeter and a low value means the extruder will be moved just before the beginning.
The "Jitter Over Extrusion Width (ratio)" is the ratio of the amount the loop ends will be jittered. A high value means the loops
will start all over the place and a low value means loops will start at roughly the same place on each layer. To run comb, in a
shell type:
> python comb.py
The following examples comb the files Hollow Square.gcode & Hollow Square.gts. The examples are run in a terminal in the folder
which contains Hollow Square.gcode, Hollow Square.gts and comb.py. The comb function will comb if 'Activate Comb' is true, which
can be set in the dialog or by changing the preferences file 'comb.csv' in the '.skeinforge' folder in your home directory with a text
editor or a spreadsheet program set to separate tabs. The functions writeOutput and getCombChainGcode check to see if the
text has been combed, if not they call getTowerChainGcode in tower.py to tower the text; once they have the towered text, then
they comb. Pictures of combing in action are available from the Metalab blog at:

> python comb.py
This brings up the dialog, after clicking 'Comb', the following is printed:
File Hollow Square.gts is being chain combed.
The combed file is saved as Hollow Square_comb.gcode
