We upgraded the TAZ6 with a dual extruder. Everything seems to be working but the print quality is terrible- for printing both dual and single extruding. What do I need to adjust/change to get a good print? I am trying to attach a photo–left in photo is with original single extruder, right is with dual extruder using back nozzle.

I am having similar issues. I have been thinking about going to the Dual Extruder V3 because of all of the issues I am having with the V2 but it sounds like V3 may be even worse.
