Thanks for the reply!! I actually tried all the above already, i printed up to 0.27mm at speed of 60/70 mm/s reducing the layer time to zero but no luck. I even thought that the filament could have absorbed moisture and bought a new one but still had the same issues.
Its kind of strange as I often print with woodfill and never have issues.
I'll keep on doing attempts and keep you updated.
Thanks anyways!!
