I hope someone can help me with this. I have the dual head on my Taz 6. When I go into Cura to set up my print it will print from both heads if there are two separate entities. However, when I try to print support (touching buildplate or everywhere) and I select second extruder it will not recalculate the model. If I select First extruder, it will select and recalculate, likewise with both, but it will not use the second extruder (which I have loaded with HIPS) for the support. It will continue to use the First extruder with the ABS for the support. Has anyone else run into this problem? Have you fixed it?
