Posted · Blobs at the start of a new layer

Hey there guys i am reasonably new to the 3D printing world and have been coming across a lot of print problems but this new problem is one i haven't managed to figure out on my own so i need some help. The problem I'm having is a massive blob of filament comes out at the start of each new layer and in most cases is causing my nozzle to block. If the blobbing doesn't occur the prints come out very good. I have tried different retraction settings, speeds, temperatures, flows, extruder e/steps, changing the bowden tube etc and cant get this problem to go away. I have attached some photos (sorry about the quality) and maybe someone in the community has seen this problem before.

 

Thanks in advance,

Matt
