This document is intended to describe each of the presets parameters used to slice a model with Zim.
|
Layers and Perimeters
|
Layer Height
|
Layer Height
|
Controls the height (and the total number) of the slices or layers. Thinner layers give more accuracy but take longer to print
|
|
|
|
First layer height (mm or %)
|
Controls the height of the first layer. For building with very low layer height it may be preferable to set a higher first layer to improve adhesion and tolerance for non-perfect build plates
|
|
|
Vertical shells
|
Perimeters (minimum)
|
Sets the number of perimeters to set for each layer
|
|
|
|
Spiral vase (on/off)
|
This will raise z gradually while printing a single-walled object in order to remove any visible seam. If this option is turned on other settings will be overridden to enforce a solid perimeter, no infill, no top solid layers as well as no support material. |
|
|
Horizontal Shells
|
Solid Layers (top, bottom)
|
Sets the number of solid layers to set on the top and bottom
|
|
|
