Jitter jitters the loop end position to a different place on each layer to prevent the a ridge from forming.<br>

The default 'Activate Jitter' checkbox is on. When it is on, the functions described below will work, when it is off, the functions will not be called.<br>

<a name="Jitter Over Perimeter Width" id="Jitter Over Perimeter Width"></a><h3>Jitter Over Perimeter Width</h3>
Default is two.<br>
<br>
Defines the amount the loop ends will be jittered over the perimeter 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>

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>

This brings up the jitter dialog.<br>
