2. Initial Layer Height
Initial layer height determines the first layer height of your print. More often than not, the initial layer
height is thicker than the remaining layers to create a stronger bond to the build platform by laying down
a bit more plastic onto it. This helps the print not come loose from the bed when printing the rest of the
model. If you have a raft (build plate adhesion option) enabled, your initial layer height can be the same
as your layer height. If you do not have a raft enabled, it is best to use a thicker initial layer height.
3. Line Width
Line Width determines the width of a single printed line. Normally, the line width should equal the
diameter of your nozzle for most prints. Cura for Robo will automatically calculate how much plastic
should flow out of the nozzle based on line width.
Left: smaller line width - Right: larger line width

1. Wall Thickness
Wall thickness determines how many walls (or perimeters) your print will have. Set this value to be a
multiple of line width from the section above. The larger your wall thickness, the sturdier your print will
be, but the more time it will take to print. An average wall thickness is about 3 times your line width.
Left: 3 walls - Right: One wall
2. Wall Line Count
You can also set a wall line count if you do not want to set your wall thickness. The wall thickness will
be automatically calculated if you enter a wall line count number into this field based on your line width.
3. Top/bottom thickness
The top/bottom thickness setting will determine how many solid (fully filled in) layers of plastic you will
print on the top and bottom of your print. The higher the thickness count is, the less gaps you will see
in the top and bottom layers, but will increase print time and use a bit more filament. When setting this
value, set it as a multiple of your layer height to ensure even distribution of plastic. For thicker layer
heights (.2 mm), .6 or .8 mm thickness should be sufficient. For thinner layer heights (.1 mm), use .8 or 1
mm thickness to get a clean top and bottom layer.
