Retraction and Stringing Test (improved)

This version of the retraction test has thicker towers to reduce issues which can cause stringing even when retraction settings are dialed in. Print time = 20minutes at 40 mm/s

If you've tried various retraction settings and still have issues, 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.
