I’ve been dipping my toe into the multi-material stuff, and have been printing the demo chip clips from the Cura folks. They’re coming out fantastic… however, I am getting a TON of stringing between the prime tower and the model, but just with the TPU. For some of them, it’s almost like it was bridging, and extruding the entire distance between the model and the tower
Sorry for the potato quality picture, waiting for the Raspi v3 camera to arrive.
Put your TPU in a dryer for several hours. It is not as bad as Nylons when it comes to moisture absorption, but TPU turns into a blobby, stringy mess when it is wet.

Appreciate the feedback - I’ll give the TPU a good cook at some point, but I don’t think it’s moisture, as other prints turn out spectacular. No stringing, no issues at all. This is the only time I have a problem with TPU, on this one particular print. It’s the only one that uses a prime tower, and I haven’t had a chance to verify what the extruder is doing during the move, but it sure does look like it’s extruding based on the thickness of the strings. I think this is the result of a print setting.
