Dimension adds Adrian's extruder distance E value to the gcode movement lines, as described at:
http://blog.reprap.org/2009/05/4d-printing.html
and in Erik de Bruijn's conversion script page at:
http://objects.reprap.org/wiki/3D-to-5D-Gcode.php
The dimension manual page is at:
http://www.bitsfrombytes.com/wiki/index.php?title=Skeinforge_Dimension
==Operation==
The default 'Activate Dimension' checkbox is off. When it is on, the functions described below will work, when it is off, the functions will not be called.
==Settings==
===Extrusion Distance Format Choice===
Default is 'Relative Extrusion Distance'. In Adrian's description the distance is absolute, but since the relative distances are smaller than the cumulative absolute distances, I chose to make the default relative.
====Absolute Extrusion Distance====
When selected, the extrusion distance output will be the total extrusion distance to that gcode line.
====Relative Extrusion Distance====
When selected, the extrusion distance output will be the extrusion distance from the last gcode line.
==Examples==
The following examples dimension the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and dimension.py.
> python dimension.py
This brings up the dimension dialog.
> python dimension.py Screw Holder Bottom.stl
The dimension tool is parsing the file:
Screw Holder Bottom.stl
