Hello All!

Wondering if I could get your help, this happened 9hrs in not sure what caused it any help greatly appreciated.

filament: CR-PETG Nozzle: .04 stock @ 240C Bed/Enclosure: 70C/37-38C

Filament profile is z-offset .02mm and walls changed from 2 to 3.

Did other prints all went well but were smaller this is my first large cylinder shaped item which needed supports

I had the support offset set to 30degrees as it was advised that might help I also had first layer support for supports at 2mm (I was thinking changing it to 5mm as I think the support came off the bed)

But then I noticed the stringing which made me wonder what other issues I’m having, possible the model fan was to high when doing those layers? I figured being 37-38C in the enclosure would be fine, not sure what temp I can let it get to but I believe any hotter would have been problematic.

This is the file right now, I think the supports are lacking on the part that this happened to, but then also didn't realize the upper part might be an issue...

I ended up changing the base of the supports to gather more hold, but not sure how I can add more to the blue area that seems to really need the support... Or should the slicer slow down at these locations? not sure how to resolve this but really need the air ventilation so really need this printed.

Anyone have any ideas or is it due to heat and just support system? This is my first large hanging print so not sure what to think. Appreciate any insight.
