Although most models can be built using the default toolpath parameters, there
are times when certain features are too small to fill. One option would be to use
a thinner layer for the whole part, since the default toolpath width is based on
the slice thickness, but this would require changing tips on the machine and
recalibrate, and would also add extra time to the build. Therefore, the first solution
to try is to create what is known as a Custom Group. Custom Groups specify
different toolpath parameters for individual curves.
Figure 1 demonstrates inner and outer toolpaths that do not meet each other,
causing a hollow area in the center. This is an undesirable fill because the two
disconnected walls will be weak. However, this condition can be corrected by
modifying the toolpath widths. Both the Contour Width (the “outline” of the part)
and the Raster Width (the zigzag fill inside the part) can be changed separately.
There are two ways to fix this problem. The first method, is to measure the total
width of the wall and make the contour one-half of the total width (figure 2).
Modify Tool Path Widths
STEP 1: Select “Custom Groups” from the Toolpaths menu click on “New” to see the toolpath parameters popup box.
STEP 2: Select a different size from the drop-down menu next to Contour Width and click on the green check mark
STEP 3: Drag the cursor over the curves to select them.
STEP 4: Click on the “Add” button to apply these new parameters to the selected curves.
