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.

The jitter manual page is at:

Operation

  Jitter Over Perimeter Width
Examples

Operation

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.

Settings

Jitter Over Perimeter Width

Default: 2

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.

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.


Examples

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.

> python jitter.py
This brings up the jitter dialog.

> python jitter.py Screw Holder Bottom.stl
The jitter tool is parsing the file:
Screw Holder Bottom.stl
..
The jitter tool has created the file:
.. Screw Holder Bottom_jitter.gcode
