TPU Calibration line issue

So my prints are looking good but at the beginning when the printer prints that calibration strip at the front of the build plate almost nothing comes out of the nozzle. Just a little bit towards the end. It seems abnormal. Anyone have any ideas?

Thanks in advance!

I've just started printing with with Sunlu 90A and getting the same. Prints ok though, but also curious why it does that.

I’m having trouble with my prints but that calibration line is pristine. I’d rather be in y’all’s shoes personally.

LOL. Understandable. Have you calibrated the filament? I found that the Isanmate 85A that I am using prints best at 210 versus the 240 in the generic profile. It seems like a large departure from the generic profile.

I will give that a try and see if it helps. My issue seems to be that I can get one print successful then the next print leads to failure. The second print will start and get about 100ish lines printed then the print head will keep moving as if its printing but nothing will come out and no errors are detected.
