Dual Extrusion
-Wipe & prime tower volume per layer:
The wipe-
tower is a tower printed on every layer when switching
between nozzles.The amount of material put in the
wipe/p rime tower. This is done in volume because
in general you want to extruder a certain amount of
volume to get the extruder going, independent on the
layer height. This means that with thinner layers, your
tower gets bigger.
Retraction
-Minimum travel:
minimum amount of travel needed
for a retraction to carry all. To make sure you do not
get a lot of retraction in a small area, value = 2 is
recommended as best performance, too small will lead
to frequent retraction.
-Enable combing:
combing is the act of avoiding
holes in the print from the head to travel over. Enable
combing extruder will always touch the surface of
model but disable retraction. If combing is disabled
the printer head moves straight from the start point to
the end point and it will always retract. Default enable
coming, but it will increase printing time.
-Minimal extrusion before retracting:
The minimal
extrusion that needs to be done before retracting again.
If a retraction needs to happen before this minimal is
reached the retraction is ignored. This avoids retraction
a lot on the same piece of filament which flattens the
filament and causes grinding issues. Recommended
0.02 at best performance, 0 means unlimited retraction
frequency.
-Z hop when retracting:
See function prompt in the
software.
Parameter Definition
Expert Setting
Skirt
-Line count:
The skirt is a line drawn around the object
at the first layer. This helps to prime your extruder, and
to see if the object fits on your platform. Recommended
setting is 1 with best performance. Setting this to 0 will
disable the skirt. Multiple skirt lines can help priming
your extruder better for smaller objects.
-Start distance:
The distance between skirt line and
model. Default distance is 3.
-Minimal length:
The minimal length of the skirt, if this
minimal length is not reached it will add more skirt lines
to reach this minimal length. Recommended setting is
260 with best performance. If the line count is set to 0
this option is ignored.
Cool
-Fan full on at height:
The height at which the fan is
turned on completely. For the layers below this the fan
speed is scaled linear with the fan off at layer 0.
-Fan speed min:
Minimal fan speed during normal
printing.
-Fan speed max:
Maximal fan speed when automatic
slowing down printing.
-Minimum speed:
minimum printing speed of
each layer. Recommended setting is 10 with best
performance. Too slow will result in nozzle oozing.
-Cool head lift:
lifting the head, if the minimal layer
time is not enough, to extend the cooling time for
model cooling.
