Quality
Layer Height (mm):
This describes the Z distance between each layer. For a 0.4 mm nozzle, the average quality can be
achieved with a layer height of 0.2 mm. Average quality is sufficient for most prints except for items with fine details. If a
higher resolution is desired, the layer height setting can be changed to 0.15 mm or 0.1 mm.
Shell Thickness (mm):
This describes the thickness of the outer shell of a printed part. This value must be a multiple of the
nozzle size. For example, when using a 0.4 mm nozzle a 0.8 mm shell thickness is two nozzle widths.
Enable Retraction:
This setting allows the extruder to retract the filament when it is traveling between points during a
print. Retracting the filament will prevent the nozzle from leaving a residue as it travels.
Fill
Bottom/Top Thickness (mm):
This describes the thickness of the solid bottom and top layers of a part. This value must be a
multiple of the layer height. For example, a part with a layer height of 0.2 mm will have 3 solid bottom and top layers when
the input is 0.6 mm for this parameter.
Fill Density (%):
This describes the amount of infill that will be printed in a part. Typically, an infill of 20% is sufficient
internal support to make a strong part. Increasing the infill to 70% will make an almost solid part. Click on the
“…”
button to
show the Expert config window. In this window, the top and bottom layers can be turned off. For example, a vase can be
made by turning the solid infill top to off and setting the fill density to 0%.
Speed and Temperature
Printing speed (mm/s):
This describes the nozzle speed while printing.
Printing temperature (°C):
This describes the temperature of the hotend while printing. This value can be adjusted
depending on the material being used. PLA should be set between 200 °C - 210 °C.
Bed Temperature (°C):
The TKI Kossel Model A does not have a heated bed. This value can be ignored for the TKI firmware.
