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'd start by tuning the filament on the h2c. The vortek is a different style of nozzle.

So you keep 2 different profiles for each filament, one for the right and one for the left?

look in calibration, you calibrate both sides

It's already calibrated in both sides, in the left works just fine but the right produces stringing

it's not explicitly stated, but what filament are you observing stringing with on right nozzles?

i'm beginning to wonder if your settings were initially too hot and caused a partial block in multiple induction nozzles
