Taz 6 Dual Extruder only use T0

Hey gang, I’m new to the Taz 6 and 3d printing in general, but I’d like to do something similar where I just use the T0 nozzle for printing and not even bother with T1. When I try both nozzles heat no matter what. I’ve tried other things, changing various code options (don’t know what I’m doing), but they all ended in failure. I’m not familiar with coding, but from what I understand from this thread: https://forum.lulzbot.com/t/use-only-one-extruder-of-dual-extruder-v2/3618/1 . There’s a specific start and end gcode that I need to use if I only want to print with the T0 nozzle. Can anyone enlighten me as to what the start and end code should be for this :question: Thanks!
