This first print is going great! Hopefully it stays that way 
@NWCC @thefistpump and anyone else with the X2D. I see you are doing full PLA supports for TPU. Are you doing full PLA supports for PETG as well? Interface and Base?
For PETG parts, most of the time I am just using PLA for the interface layer. From what I have seen for the TPU stuff its best to use PLA for the complete supports but I might try it as interface layer. This is my first print with the TPU using PLA for supports so hopefully someone with more experience will chime in. Note that this is not limited to just the X2D. The H2D, H2C and Snapmaker U1 can do this as well. Basically any printer with more than one nozzle/extruder can do it.

I’m only using PLA support for the TPU Handle grip at the moment, I need to do this for the cushion inserts as well, but have not yet.
For PETG, I’m leaving it to PETG supports just to keep it simple. Hasn’t been much of an issue.

I top load all my machines to print TPU. The small piece of PTFE tube at the extruder is only to protect the filament from rubbing on the cable chain.

I have a Bambu Lab P1S and P2S, which I use with the Creality Space Pi Filament Dryer Plus.
I was having a really hard time printing the TPU parts. No matter what I tried, it always came out looking like it had acne 
There were pimples and string all over it. If I tried clipping the pimples off, it left dimples and pock marks. The headrest and seat back threatened to steal the last ounce of my sanity! I tried calibrating, slowing it down, drying it for 24 hours, multiple different brands of TPU. I almost gave up.
Then I purchased the Bambu Lab TPU Feed Assist Module… ABSOLUTE GAME CHANGER 
I can now print all the TPU files as-is, no adjustments, no supports, no problems! They all come out perfectly smooth. I’ve even been turning the speed up to Sport Mode in the places where it’s not printing around the holes. The TPU Feed Assist Module is worth its weight in gold!

So basically what you are saying is that the issue is with feeding the TPU to the print head?
Once you had that solved, the other settings weren’t the issue.
I have one on my X2D now and its been great! Playing around with PLA supports so things come out super clean!!
That looks to be the case. Without the assist module, I see the extruder struggling to pull the TPU. It pulls tight, under extruding, then suddenly pings slack again, over extruding, which seems to cause the pimples and stringing.
The assist module looks to be just an additional extruder. I can see it pulling tight then pinging slack again on the spool, but it is smoothly feeding to the main extruder in the tool head.
The results on the TPU prints is like night and day. It used to be my nemesis. It’s now so easy that I’ve volunteered to print those files for a friend who also makes 3D-TMTs

Same! I added one to my H2D right before starting all of the handle/strap/etc. TPU prints for my 1st TMT build and it made it so nice to be able to just throw rolls in to the AMS-HT (so you can dry while printing also if desired) and not worry about where it was positioned or agonize over making “the most frictionless path” to get clean results. It made TPU printing feel like printing any other type of filament.
