Strings with Dual Extrusion

[dcschooley 9]

What is the most reliable way to get rid of the strings in at the attached photograph? This is a 27-hour print and I have three more to do. I am going to try an ooze shield for the next one. I am already using a prime tower. I'm using Alloy 910 with Matterhackers Ionic. (Yes, the image might be upside down. I don't know why.) I have reduced the standby temperature but it didn't seem to help.

You using a "Prime Tower"?

if this filament is PA based and/or the support is PVA, these strings might be related to moisture. You need to thoroughly dry your filaments and keep them dry, this will make the filament's flow more predictable and it will ooze less. you might also want to tune your retraction settings if not already.
