Retract settings in sli3er?

Getting some really nice prints having gone back to basics and rechecked all callibrations but now I am noticing threads whenever the print head travels to a new print position so was wondering what retract settings everybody uses.

Tried 5mm retract on a 20mm test cube but the print turned out worse as the print head stopped on the corner as it retracted and left more melted abs when it stopped.

Just finished printing a whiste and the inside is full of threads and the ball is stuck firmly inside.

I slowed down the DEFAULT_RETRACT_ACCELERATION in Marlin from 3000 to 1200. In Slic3r, I reduced the retraction to 0.5mm, reduced retraction speed down to 10mm/s and turned on Z Lift by setting it to 0.1mm.

This is what works great for me...

Thanks for the advice.

I also just upgraded my version of slic3r. Like the new look.

Your settings work perfectly.

Now I just have to stop large prints lifting on the extremities and I'll be right.
