Typically, just slowing the print itself down will take care of a lot of common issues. You can dial the retract details from there. Get good results and proper dimensions on your test piece and you have a good "detail" profile for whatever filament you are running. Now you can start speeding it up and see what your print quality limits are before a little more tweaking needs to be done on the other dials. It really does test the patience of the most hardened geeks and they are relentless! (No offence to geeks = cred')
