When in Standard mode, the Raft setting was simply an on/off setting. In Advanced mode,
you've got a lot more control over how the raft is laid down.
Expand Distance is the distance you'd like the raft to exceed the base area of the part you're
printing. You may want to adjust this parameter if the part you're printing is larger than the bottom
contact point on the bed. A larger raft will help to support the part more effectively.
Air Gap defines how much space you want between the top surface of the raft and the bottom
surface of your part. This gap helps make it easier (or even possible!) to remove the raft from your part
when it's finished. As mentioned in the help text, a good air gap is one half the diameter of the nozzle.
For example, if your nozzle is 0.5mm, you'd want an air gap of 0.25mm.
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 Rostock MAX, 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.
