When
Avoid Crossing Perimeters
is enabled, the nozzle path will not cross a part
perimeter during travel moves. This will help reduce the opportunity for stringing or oozing since
the nozzle tip is rarely over open air. For instance, if the tool path would normally cause the
nozzle to travel from one side of the part to the other, it would cross at least two perimeters and
may leave strings of material in its wake as it moves. If it is set to not cross perimeters, it will
cause the nozzle to trace a perimeter back to the nearest point where it can begin printing again
instead of jumping straight across to the new extrusion position.
Spiral Vase
mode allows you to print things like vases or other open top, single-wall
objects in one continuous layer. What happens is that instead of the slicer raising the nozzle up
a full layer height for each new layer, it gradually increases the Z height as the print progresses.
This results in a perfectly seamless object, which can be important for artistic prints such as
vases. When you're printing a vase or similar object, you'll want to make sure that you set the
top layer count to zero to prevent the vase getting a “lid” that you'll have to cut off.
By default, objects are printed from the inside features to the outside. If you want to
reverse this process, enable
External Perimeters First
. This will cause the outside of the
model to be printed before the interior features.
The
Top
and
Bottom
solid layer parameters dictate how thick the top and bottom
surfaces of your object are when printed. These two parameters fulfill essentially the same
function as the
Perimeters
parameter, but for the top and bottom of the part. You can calculate
your top & bottom thickness by multiplying the solid layer count by the layer height. For
example, 5 top layers will result in a final top thickness of 1mm if your layer height is 0.2mm.
You also have the option of specifying an exact thickness in millimeters, using the same “mm”
suffix used in the
Perimeter
field.
