This craft tool jitters the loop end position to a different place on each layer to prevent a ridge from being created on the side of the object.<br>
<br>

<a name="Operation" id="Operation"></a><h2>Operation</h2>
<hr>
The default 'Activate Jitter' checkbox is on. When it is on, the functions described below will work, when it is off, nothing will be done.<br>
<br>
<a name="Settings" id="Settings"></a><h2>Settings</h2>
<hr>
<a name="Jitter Over Perimeter Width" id="Jitter Over Perimeter Width"></a><h3>Jitter Over Perimeter Width</h3>
Default: 2<br>
<br>
Defines the amount the loop ends will be jittered over the edge width. 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.<br>
<br>
For example if you turn jitter off and print a cube every outside shell on the cube will start from exactly the same point so you will have a visible "mark/line/seam" on the side of the cube. Using the jitter tool you move that start point around hence you avoid that visible seam. <br>
<br>
<br>
<a name="Examples" id="Examples"></a><h2>Examples</h2>
<hr>
The following examples jitter the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and jitter.py.<br>
<br>
> python jitter.py<br>
This brings up the jitter dialog.<br>
<br>
> python jitter.py Screw Holder Bottom.stl<br>
The jitter tool is parsing the file:<br>
Screw Holder Bottom.stl<br>
..<br>
The jitter tool has created the file:<br>
.. Screw Holder Bottom_jitter.gcode</tt>
