TPU Infill Foam style Prints rapidly get worse in latter half of a print
I've been trying to test out a TPU "foam" style by printing objects without walls and just infill. Unfortunately I can't seem to dial in the right settings for it. They consistently start to fail around the second half of the print and I'm unsure why. I've tried multiple temps and cooling levels but it's pretty consistently failing within the top half of the test print.
Printed on a qidi xmax 3, no walls, 50mm/s, .2mm layer height
220c first layer 230 after, 10% cooling max with 50% on overhangs.

Yeah something's also going on in general. The second layer of this attempt had what appears to be significant underextrusion and the fan is making a buzzing noise. I swear I can hear the printer trying to raise and lower too when it does the underextruded parts as well so maybe that's having something to do with it
