When I had my single extruder attached and was running Cura there were options on the quick print screen labeled “Quick print”, “Standard” and “Quality Prints”.
These options are not available when Cura is set for a dual extruder. So instead you have to switch to “Expert Print”. The problem with this is it does not give you the ability to select your materials. In the “Expert Settings” I have been able to shrink the layer widths from 0.38 to 0.2 which seems to make an ok print but not nearly as good as using the “Quality Prints” setting available with the single extruder.
Does anyone know how to create a profile with the proper settings for a “Quality Print” that I can use while also being able to choose my materials properly?
