Hi, we are using latest Luban and a Snapmaker J1. The copy/mirror mode with the 2nd extruder work fine. But whenever we tried to print with the 2nd head support material (1st PLA, 2nd PVA; 1st PET-G 2nd PVA; 1st PA 2nd PET-G) or what so ever, the 2nd extruder is just doing …******… stays on the right side of the bed, drives fwd/aft (not left/right) when it is supposed to print and just creates a blob of material.
Seems to be independent what I select for the 2nd extruder operation type in LUBAN.
Any idea?
