Larger models apparently become flow rate limited for the material. I'm surprised this model is considered "larger". My alternatives are to reduce MVS until it works, which increases print time, or find a TPU material with a higher MVS. Most filament suppliers don't tell you this number. But I think it is possible to calculate it based on nozzle size and layer thickness. On the hunt for a better flowing TPU, it seems there are some newer versions on the market. Whether their MVS is really higher, well I will have to calculate it, or measure it. But it is worthwhile to find a better MVS as it translates to faster print times.
@brino I have had to play with temperature. It seems TPU doesn't care about enclosures, or that is what I have read. Don't have an enclosure yet, I need to print parts and haven't gotten a round tuit.
As for a trusted supplier, who knows if any of them really are trusted. I tried Amazon Overture TPU, that's the green stuff in the picture, and Sainsmart TPU. I reverted to the Overture, because I had successfully printed with it before, although not with as large of a model. The Sainsmart allegedly has a higher MVS. (May have used too high of a tension for the Sainsmart.) But maybe it isn't an MVS problem. 3d printers seem to have a whole lot of knobs to tweak, and it's not apparent to me which one's to try or avoid.
