PLA/PHA Stringing

Try cooler printing.
Potentially all spools vary for their best/optimum temperature, but generally spools from a given source are usually similar.
Still, try running a test print a little bit cooler and see if that helps. For me, PLA usually starts to string when it is running hot.

 

I haven't seen any differences with respect to stringing stringing between PLA/PHA and other PLAs I've used. So, you should be fine with just dialing in temperature. Retraction shouldn't need to change that much.

Mark's advice is probably spot on. However, on the 3DPDP (Afinia and Up!) forums, the Australian colorfabb reseller did some interesting work with running the material much higher (like 235). Those machines have some trouble with temperature settings at lower values. He found things worked well at lower temperatures and higher temperatures, but there was a middle range that caused some trouble. I think at the lower temps, the material is viscous enough that you're minimizing oozing and at higher temps, it's liquid enough that the strings snap easily.
