Blobs on Perimeters

Hey guys,
Got a problem with blobs on the perimeters and I have no clue where this comes from.
The printer is freshly calibrated for Temp, Flow, PA and Retract.

About my setup:
V-Core 3.1 300mm (enclosed)
RatRig Toolhead with Orbiter2.0 and Rapido 2 UHF (stainless steel Nozzle)
Filament: BambuLab PLA Matte (fresh roll, checked it on my X1C but no issues there)

Parameters:
Temp: 200°C
Retract: 0.4mm with 240mm/s retract speed
PA: 0.020
Flow: 0.9508

Maybe somebody has an idea what I could check - I have no idea anymore.
