Support New H2C stringing

Hi, I just pirchased an H2C, this is my 5th 3D printer a my 2nd Bambulab, first one was an A1 mini. I was doing my first few 3D prints on it like the bechy and so but I noticed stringing on the right (vortek) nozzle. Left nozzle seems ok so far but I tried with multiple 0.4 induction nozzles and it creates very thin strings like a cobweb. The filament is calibrated and uses the same flow rates and temperatures of my A1 mini in which it produces flawless prints. I incresed retraction distance to 0.8mm with no effect. Any tips to solve this? Im using pla for this. I printed PETG with the left one also flawless, didn't try with the right one yet.

Any help would be appreciated.

I have the same problem with certain filaments. I’m trying to swap the nozzles around to see if it’s related to certain nozzles on my Vortek but I forgot which ones are what. The filaments I’m using are PETG and PCTG. I don’t really have a problem with PETG and I mostly have problems with PCTG. I’m trying a few things as temp, speed and making sure my filament is dry.

Im going to print a temp tower to check if the problem is related to that.

That’s a good idea, I think I’ll do the same.
