I am new to TPU. I have just loaded a reel of Inland TPU it does not state what variation of TPU it is but I can verify it’s pretty elastic when I pulled on the start of spool scrap. Since the X1C can not do a calibration on TPU I have gone with generic. The first print a benchie is rolling out now and what I have seen is some stringing but minimal but more concerning is that it appears that filament seems to come out in small random blobs around the plate and on the Flow Dynamics calibration process. Not sure if that even matters since I don’t think the LIDAR can scan a semi-translucent filament. Can anyone share any settings you may have for Inland TPU Translucent ? UPDATE: To attach final product.
Looks pretty good but the cooling settings look off. Here’s what I have for all my TPU filaments although none of them are Inland brand. I also use 0.4mm retraction which may help with your stringing. Placing the part on the left side of the bed in front of the Aux fan will also help with bridges and overhangs.
You’ll want to use the manual calibration tools to dial in the Flow ratio and Pressure advance as these shiny filaments have trouble with the LIDAR auto cal. I get wildly different results with different TPU brands and colors.

I have made your cooling settings changes. I have had input on some FB groups today stating to go from .8 to 1mm for retraction so I split the difference and went to .6. I have put my TPU away don’t like the idea of keeping it in the open on the back of the machine (no AMS) so next time I print I will either go down to .4 or go up to .8 and see if I can get any improvement if .6 is still not it.
As far as manual calibration I did do one last night for Flow Dynamics and it was a disaster! LOL The translucent red just did not cut it BUT I think .125 was the best of the blobs… I saw many blobs on each line and most of the lines were broken up. The best of them all was .125 which is an odd numbers but hey… I got a pretty good print afterwards. SLOW as hell but it was a good print.
