Topic: How can I fix blobs on outer perimeter?

So this is what is happening https://www.youtube.com/watch?v=xDS8rBnA1U0

I run a E3D v6 with a bowden extruder I use 4,5 mm reatraction at 40mm/s. Print speed is 55 mm/s layer height 0.3mm and temprature 190°C (I run cheap but decent quality no name PLA). My flow rate is spot on. I also tried costing everything from 0,2mm to 0,5mm but it didnt help either. If you have any ideas why this is happening let me know down below.  Thanks for reading.

Re: How can I fix blobs on outer perimeter?

I would say temperature related. Try lowering the temp by 5 and see if it improves. Blobs are usually caused by oozing.
