KISSlicer vs Slic3r
Canvas offers two slicing engines: KISSlicer and Slic3r, which include some different features and characteristics. This articles detail differences between the two engines in terms of the project settings they offer - more detail for all of those settings can be found in Canvas, by hovering over the appropriate setting.
KISSlicer Only Features
General:
Avoid backtracking on solid layers: turning this setting on will cause all solid surfaces to be printed from one side of the part to the other.
Layer Height
Variable layer heights: this setting allows the slicer to automatically and smoothly change between a minimum and maximum layer height.
Extrusion
Gap fill threshold: gap fill extrusions must be longer than this setting to be printed
Always retract when travelling more than: any travel movement after a print line greater than this value will always retract and wipe
Perimeters
Coast distance: coasting allows the printer to slow down and stop extruding as it nears the end of an extrusion line
Seam randomization spread: this setting allows randomness to introduced in the placement of seams
Temperature and Cooling
Perimeter fan speed: if your printer supports it, set the fan speed when printing perimeters and gap fill
First Layer
A number of raft settings relating to layer heights and speeds, among other things, are only available in KISSlicer.
Generate support interfaces above rafts: if checked, support interfaces will be placed between the top of the raft and the bottom of the model
Supports
Reinforcement layers: if enabled, support layers will alternate their orientation on one layer per interval
Horizontal inflation: specify the amount that supports should extend horizontally past the outside of the models
Slic3r Only Features
General
Top shell thickness: specify the thickness of the top shell of your model
Avoid crossing perimeters: attempt to stay within the region of a printed boundary while travelling
Solid layer styles: select the style to use when generating top and bottom solid layers
Ironing: ironing smooths out top layers by travelling along them and re-extruding a small amount of filament to fill the troughs between extrusions
Perimeters
Outer perimeter speed: specify the print speed used during outermost perimeters
Perimeter extrusion width/Outer perimeter extrusion width: specify the extrusion width for perimeters/outer perimeters
Temperature and Cooling
Bridging fan speed: If your printer supports it, set the fan speed when printing bridges
First Layer
First layer size compensation: inset all perimeters on the first layer by this distance
Supports
Support speed: specify the speed to use when printing support structures
Interface speed: specify the speed to use when printing support interfaces
