Just got a Taz 6 with Aerostruder, but it is clogged with unknown filament. What is the best way to clear an unknown material clog? I’ve run the temp up to 270° and tried to extrude, but no luck.

If it’s charred material in there, some cold pulls might help, but running it at 270 may have burnt PLA, PETG or other materials into the walls of the nozzle.

If a few cold pulls don’t clear it, for the cost of a nozzle, it’s not worth trying to get the glazed, burnt filament out. Just follow standard nozzle removal, and heated tightening of the new nozzle to replace it.
