then select that ring section. The X axis can be moved in a similar fashion.
The Z axis movement control operates similarly, but the movement scale
is dierent. The Z axis will move in 0.1mm, 1mm and 10mm increments.
The top half of the movement bar will move the Z axis up, by the selected
units, while the lower half will move the Z axis down, by the selected units.
1.26 CAD and 3D Modeling Software
LulzBot is not distributing a CAD or 3D modeling software package. How-
ever, multiple free/libre software packages are available. Other common
non-free CAD and 3D modeling software are also capable of exporting the
required .STL les.
On some CAD and 3D modeling software you will need to select
millimeters as the output unit. If possible it is best to build your 3D design
in metric units rather than imperial units. Slic3r requires .STL les sized
in millimeters. If an .STL with inches as units is loaded into the Slic3r, the
model will be scaled much smaller than expected. You can scale the model
by 2540% to compensate. The software listed below outputs millimeters as
the unit by default.
FreeCAD
Website: http://www.freecadweb.org/
Although still in development, FreeCAD is a great free/libre CAD
application. Containing a full GUI for building CAD models, FreeCAD
is capable of creating simple to complex designs. STL les can also easily
be exported for use with 3D printing. FreeCAD is available for GNU/Linux,
Windows, and Mac. The latest development version is recommended.
OpenSCAD
Website: http://openscad.org
OpenSCAD is another free/libre CAD software; however, dierent than
FreeCAD, it is script based. Rather than using a GUI to generate CAD
designs, OpenSCAD CAD designs are created using script based renderings.
Users with programming experience would nd this very useful. Also,
OpenSCAD uses a simple script language that is easy for users with little
