Allan Ecker aka The Masked Retriever's has written two quicktips for raft which follow below.<br>

<br>
Raft is based on the Nophead's reusable raft, which has a base layer running one way, and a couple of perpendicular layers above. Each set of layers can be set to a different temperature. There is the option of having the extruder orbit the raft for a while, so the heater barrel has time to reach a different temperature, without ooze accumulating around the nozzle.<br>
<br>
The important values for the raft settings are the temperatures of the raft, the first layer and the next layers. These will be different for each material. The default settings for ABS, HDPE, PCL & PLA are extrapolated from Nophead's experiments.<br>

<br>
<a name="Raft Size" id="Raft Size"></a><h3>Raft Size</h3>

Default is 0.9.<br>
<br>
Defines the ratio of the flow rate when the support is extruded over the operating flow rate. With a number less than one, the support flow rate will be smaller so the support will be thinner and easier to remove.<br>
<br>
<a name="Support Gap over Perimeter Extrusion Width" id="Support Gap over Perimeter Extrusion Width"></a><h4>Support Gap over Perimeter Extrusion Width</h4>
Default is 0.5.<br>
<br>
Defines the gap between the support material and the object over the perimeter extrusion width.<br>
<br>
<a name="Support Material Choice" id="Support Material Choice"></a><h4>Support Material Choice</h4>
Default is 'None' because the raft takes time to generate.<br>
<br>
<a name="Empty Layers Only" id="Empty Layers Only"></a><h5>Empty Layers Only</h5>
When selected, support material will be only on the empty layers. This is useful when making identical objects in a stack.<br>
<br>
<a name="Everywhere" id="Everywhere"></a><h5>Everywhere</h5>
When selected, support material will be added wherever there are overhangs, even inside the object. Because support material inside objects is hard or impossible to remove, this option should only be chosen if the object has a cavity that needs support and there is some way to extract the support material.<br>
<br>
<a name="Exterior Only" id="Exterior Only"></a><h5>Exterior Only</h5>
When selected, support material will be added only the exterior of the object. This is the best option for most objects which require support material.<br>
<br>
<a name="None" id="None"></a><h5>None</h5>
When selected, raft will not add support material.<br>
<br>
<a name="Support Minimum Angle" id="Support Minimum Angle"></a><h4>Support Minimum Angle</h4>
Default is sixty degrees.<br>
<br>
Defines the minimum angle that a surface overhangs before support material is added.<br>
<br>
<a name="Alterations" id="Alterations"></a><h2>Alterations</h2>
<hr>
If support material is generated, raft looks for alteration files in the alterations folder in the .skeinforge folder in the home directory. Raft does not care if the text file names are capitalized, but some file systems do not handle file name cases properly, so to be on the safe side you should give them lower case names. If it doesn't find the file it then looks in the alterations folder in the skeinforge_tools folder. If it doesn't find anything there it looks in the craft_plugins folder.<br>
<br>
<a name="support_start.gcode" id="support_start.gcode"></a><h3>support_start.gcode</h3>
If support material is generated, raft will add support_start.gcode, if it exists, to the start of the support gcode.<br>
<br>
<a name="support_end.gcode" id="support_end.gcode"></a><h3>support_end.gcode</h3>
If support material is generated, raft will add support_end.gcode, if it exists, to the end of the support gcode.<br>
<br>
<a name="Examples" id="Examples"></a><h2>Examples</h2>
