print slower and increase retraction length and speed.
You've got a direct drive extruder so you can run retractions at up to 70mm/s quite happily.
Retraction distance wise start at about 2mm and work your way up untill you stop getting blobs.
So make sure you have retraction ON for layer changes as these are often where blobs appear.

Also try tweaking the printing temperature.

I've seen people claim everything from 225c on up to 255c for best temp for pet-g. So it pays to experiment.

Speed wise, the general consensus is 40mm/s maximum and always adjust downwards.

To get your first layer stuck - run it slightly hotter and a lot slower - say 5% of the maximum speed.
Yes that is SLOW. And frequently your first layer is 50% or more of the total print time - but if it works - who cares :-)
