Taz 6 Dual Extruder gcode questions

Hi all,

I’m trying to get the dual etruder setup and have a couple of questions.

  1. This seems pretty basic, but I can’t find it anywhere. Is there a command in the Cura control interface to show what g-code is being sent?
    After cleaning, the head moves to it’s heating up position, but then the front extruder extrudes a bunch of filament into mid air while it’s waiting.

  2. What’s the difference between “start.gcode” and “start2.gcode”? I have a feeling to figure out #1 I’m going to have to tweak one or both of those, but I can’t tell what’s the difference or when when or the other is called.
