Comb is a script to comb the extrusion hair of a gcode file.<br>
<br>
The comb manual page is at:<br>
<a href="http://www.bitsfrombytes.com/wiki/index.php?title=Skeinforge_Comb">http://www.bitsfrombytes.com/wiki/index.php?title=Skeinforge_Comb</a><br>
<br>
Comb bends the extruder travel paths around holes in the slices, to avoid stringers. It moves the extruder to the inside of perimeters before turning the extruder on so any start up ooze will be inside the shape.<br>

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.<br>

<br>
<a name="Minimum Departure Distance over Perimeter Width" id="Minimum Departure Distance over Perimeter Width"></a><h3>Minimum Departure Distance over Perimeter Width</h3>
Default is zero.<br>
<br>
Defines the ratio of the minimum distance that the extruder will travel and loop before leaving a perimeter. A high value means the extruder will loop many times before leaving, so that the ooze will finish within the perimeter, a low value means the extruder will not loop and the stringers will be thicker. Since it sometimes loops when there's no need, the default is zero.<br>
<br>
<a name="Running Jump Space over Perimeter Width" id="Running Jump Space over Perimeter Width"></a><h3>Running Jump Space over Perimeter Width</h3>
Default is zero.<br>
<br>
Defines the ratio of the running jump space that is added before going from one island to another to the perimeter width. The default is zero because sometimes an unnecessary running jump space is added, if you want to use it a reasonable value is five. For an extruder with acceleration code, an extra space before leaving the island means that it will be going at high speed as it exits the island, which means the stringer across the islands will be thinner. If the extruder does not have acceleration code, the speed will not be greater so there would be no benefit and 'Running Jump Space over Perimeter Width' should be left at zero.<br>
