LulzBot TAZ 5 - Skirt Settings

2.5. EXPERT MODE
• Only retract when crossing perimeters (Inll) - Tells Slic3r to
only retract if the nozzle will cross the threshold of the current island
being extruded. Slight ooze within the walls of a part are not seen
and can usually be accepted.
• Avoid crossing perimeters (Layers and perimeters - Advanced)
- Will force the nozzle to follow perimeters as much as possible
to minimise the number of times it must cross them when moving
around, and between, islands. This has a negative impact on both
G-code generation and print times.
• Randomize starting points (Layers and perimeters - Vertical shells)
- As the extruder moves up to the start of the next layer any ooze can
result in blobs. If the same start point is used for every layer then a
seam can form the length of the object. This setting will move the
start point to a dierent location for each layer.
See also subsection: Sequential Printing, on page 118 for another
technique which can minimise strings forming between objects.
Skirt
The Skirt setting adds an extrusion a short distance away from the
perimiter of the object. This can ensure that the material is owing
smoothly from the extruder before it starts on the model proper.

• Loops - How many circuits should be completed before starting on
the model. One loop is usually sucient.
