Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)
OctoPrint version: 1.3.6
Printer: Lulzbot Taz6 Dual Extruder v3
firmware: 1.1.5 marlin (?)
serial: https://gist.github.com/keawepoo/22c47721619bc147ed16c7bc2531e7b7
octoprint: gist.github[dot]com/keawepoo/003f6c5a6062f397241f959dec3d9269
terminal: gist.github[dot]com/keawepoo/316005fa0746c7548f53003a009c7212

From your serial.log it looks like you have flashed the firmware correctly:

FIRMWARE_NAME:Marlin  FIRMWARE_VERSION:1.1.5.71 EXTRUDER_TYPE:DualExtruder v3 
SOURCE_CODE_URL:https://code.alephobjects.com/diffusion/MARLIN PROTOCOL_VERSION:1.0
MACHINE_TYPE:LulzBot TAZ 6 EXTRUDER_COUNT:2 UUID:845f003c-aebd-4e53-a6b9-7d0984fde609

From the video, it looks like the gcode for that print doesn't have the correct "Start Gcode" for that Extruder. Can you post the gcode file, please.

Close, It was due to a corrupted firmware/gcode file.

Close it yourself by marking your discovery as the solution please.
