Help me print 92A TPU please?
7 years printing with MK3S+ convinced me to get a MK4 and an enclosure and I'm pretty happy with the bundle.
For the last couple of weeks, I've been printing PETG, PLA and 95A TPU without any issues but this Flexfill 92A TPU from Fillamentum is just not printing correctly.
It just came out of a sealed bag from the factory so it can be water.
I've been using the Prusa provided profile for Fillamentum Flexfill 92A but still get poor results. Any suggestions?!?

Forgot to mention using 2.7.1 Slicer and 5.1 Firmware

I've had similar issues and increasing the extrusion multiplier in Prusa Slicer helped. I increase mine to 1.1

Looks like damp filament to me. You cannot assume that filament is dry just because the roll is fresh out of the bag, unfortunately.
Try drying a length of it in an oven at 60°C for an hour and see if that prints without the blobbiness. I have some Recreus FilaFlex 82A that I have to dry immediately before each print. It seems like it sucks up water from the air more avidly than the silica jell. (Otherwise it is a really good flexible filament!)
