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.
6.2 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.. It is
important to have A.S. for printing dual material, as all the mixture of the two
materials during shifting main(1) and support (2) material will be 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.
