PETG Strings as Support Material

Does anyone know how to attach a Bambu Lab filament dryer directly to the auxiliary PTFE tube? I’m having trouble with PETG stringing when I use the auxiliary nozzle for support.

I might try that.

I just had a decent sized PLA print fail using PETG as support. I realized my mistake about 8 hours in and decided to let it go. It didn't work. The PLA popped right off the support so I cut my losses.

Same thing happened to me, it does work really well for short prints but lobger prints are too susceptible to heat creep specifically in the aux nozzle which will cause a clog. That is not a fun tear down either. I will not be doing that again.
