I have a BigBox 1.1 and I was hoping to get my first print today. I thought I would use the direct extruder as to me that makes more sense when starting out. I fed the filament through nozzle 2 (the right nozzle) and did the steps in the manual. Nothing happened. It looks like the code is for nozzle 1? How does one do the "120mm" filament length calibration on the bowden side? Pushing in the PTFE tube down into the hot-end was a nightmare. I hardly want to pull it out to measure the filament. And is Nozzle 1 really the primary nozzle for use being bowden? Do I have to hack the GCode to get this working or?
