Thanks for the reply. So when I tell Cura there is 1 extruder, it still knows that the Dual v3 is actually installed and doesnt change any of the offsets, limits, or autobed leveling gcode, correct? I know it uses the left extruder to zero on the left bed washers and the right extruder to zero on the right bed washers and wasnt sure if that gets messed up or if there are gcode considerations that need to be taken into account. I just want to keep the second extruder from heating up for prints that dont need it. Thanks again!
