Please note an Auxiliary support pillar is auto loaded with the file. This is due to the
activation of second extruder. On the left object list, two new entries appear, one is the STL
model loaded and the other is the Auxiliary support.
6.4 Auxiliary Support (A.S.)
It is a special preset object for material switching during a print. The A.S. is printed as a
column and material will be switched within the path of A.S region of the current layer. User
should able to observe a gradient of material change in A.S.. The reason for using A.S. for
printing dual material, is all the mixture of the two materials during shifting main(1) and
support (2) material are dumped into the A.S. and the support and main objects will retain
high purity of its own corresponding material. This is important as mixing the two material
not only affect the color of print, but also affect the strength of the main object and the
solubility of the support.
Auxiliary Support print setting is partially depend on the print parameter of the current print
job but its shape and path are not adjustable by users.
Due to the structure of Covergence Dual Extruder, prolonged stagnent material flow in the
hotend will casue degradation and backflow material which eventually result in clogging
of hotend.
1. Even user is printing an object that does not need any support, the Auxiliary
support(A.S) is still required for periodic material purge to prevent clogging.
2. When using the same material for both main (1) and support (2), the A.S. is still
required.
3. When printing with dual material both channels of the extruder must have filament to
prevent backflow and clogging the hotend.
