If your Orion is equipped with a layer cooling fan, you can use the
Fan Speed
setting to
cool the raft as it's being printed. This is typically only used when printing with PLA.
If you've added a second extruder to your Orion, you can specify which one should be
used for rafts by setting the
Raft Extruder
value to the index of the extruder you want to use. If
you don't have multiple extruders, you can leave this set to zero.
The
Support Material
page provides detailed settings on the use of support material if
the part you're printing requires it. While I covered the basics of support earlier, I'm going to get
a bit more in-depth on it here.
Checking
Generate Support
Material
will allow you to configure
support for your part. Support is
required when a part has an
overhang or other angled feature
that would result in little or no
physical support to put a print layer
on. The
Support Type
selection
allows you to define the geometric pattern for the support structure. You have
GRID
and
LINES
. These patterns were covered earlier, so I won't cover them again here. The new
parameter you have to work with in
Advanced
mode is called
Amount
.
Amount
is expressed in degrees from vertical and tells the slicing engine to generate
support for any feature that meets or exceeds the specified angle. In the setting shown above,
the slicing engine will generate support at points where the model “overhangs” 45 degrees or
more from vertical.
When you've got a part feature that's only 20 degrees or
so, each layer can easily be supported by the layer underneath.
This is because as the part height increases, the horizontal
dimension increase is less than the extrusion width. This means
that each new layer has a solid foundation to adhere to as it's
being applied.
As you can see when your angle increases to 45 degrees,
each layer has much less surface area to adhere to as you print.
This is where support comes in handy. It provides that underlying
structure for those layers to build upon.
