The thickness of your shells (perimeters) around your print can be decided either by giving an absolute width in millimeters, or can be calculated as a number of parallel tracks. In Pathio, shells are (by default) applied to all areas of your print: top, bottom, and sides. Unlike other slicers, this guarantees a uniform thickness on all sides of your print.
Thinner shells will weaken your print, but make it print faster and be lighter.
Thicker shells will improve the strength and surface quality of your print, but increase the time taken and amount of materials used.
Vase mode sets your model to print with a single outline that prints in a smooth, continuous motion in the Z-axis. This eliminates the start and stop points on each layer (provided you’re only printing a single object, or that your object has a single island while printing). Note that Vase mode overrides your shell thickness and infill percentage.
Controls the initial direction that the tracks on the top and bottom of your print are drawn. This is largely cosmetic. The slider controls the angle (in degrees) of rotation of the solid-fill tracks.
Controls the amount that the surface fill lines are rotated on each subsequent layer. Typically keeping this at 45 degrees is a good way to ensure your top solid layers print smoothly.
This lets you draw the solid top and bottom layers of your print concentrically, instead of the default rectilinear pattern.
Un-checking this box will use the default rectilinear patterns for the outermost layers of your print.
Checking this box will use concentric patterns for the outermost layers of your print. This pattern can look better on prints with curved surfaces.
This lets you connect your perimeters in a fluid printing motion, instead of treating them as separate tracks.
Checking this box will connect your perimeters in a spiral pattern. This removes retractions in-between the perimeter tracks and improves speed.
Un-checking this box will not connect your perimeters, and they’ll be treated as separate tracks.
