Please can you give some indication of these settings.

Please can you give some indication of these settings. Using a direct drive Extruder ( Not bowden extruder ).
What would the default Feed_rate, Acceleration, Speed MM/s be. I am getting hair strings & some blobs. PLA 1.75
Changed printing the following settings:
Temp from 195 to 216, Retraction from 1.5mm to 2.5mm , Retraction speed 70mm/sec ( not sure if the retraction speed ( simply3d ) over rights the config file setting )
Just indication of what direct drive settings would be ? feedrate etc
