Retraction and Stringing Test (improved)

thingiverse

This version of the retraction test has thicker towers to reduce issues with insufficient cooling between layers (which can cause stringing even when retraction settings are dialed in). Print time = 22 minutes at 30 mm/s If you've tried various retraction settings and still have issues, reduce nozzle temp. If that doesn't help, try doubling the value for coasting volume, and make sure "outer wall wipe distance" is set to default value or higher. Many people suggest increasing travel speed to reduce stringing--that shouldn't be necessary if all your other settings are dialed in. I've printed this with travel speed at 30mm/s (default is 100mm/s), no stringing.
