I have a BigBox 1.1 with the titan upgrade. I have one direct extruder and one bowden. Having gone over grab a copy of Alex's firmware I have the following possible choices; 1. Dual Titan 2. Dual 3. Hybrid Dual Which of these is applicable? I would have thought Dual Titan Hybrid.. but that's not there. I assume one of the three listed is what I need. But it's a toss up between #1 & #3.
