TPU gripe

Hey Prusa Fam..

My first layer of TPU 95 from elegoo looks great, smooth and goes very well. The 2nd layer doesnt even happen.. I am assuming its the retraction so I disabled it completely. I'm going to find out what happens.. I find that going into the printer settings and adjusting the flow to 150% gives me a good looking first layer.

Fun Fact: I upgraded my MK3s+ into a Mk3.9s : I have seen many different head unit designs on here and can only assume again I have the more modern/up to date one? The front facing Fan is angled outward. That being said, this is the preferred head unit for TPU?

 Why doesn't Prusa comeout with a plug and play setting for TPU? Why all this confusion? Should I have just gone with the Prusa Flex? I had no idea the the Prusa flex and the tpu 95 are the same thing.. Would that have been better for me?

 

So many questions! lol

Edit and Update:

I installed ORCA Slicer on my PC and picked the MK4S Profile since it lacked the MK3.9S Profile. I also Picked the Generic TPU Profile alongside it. And.... It prints beautifully! So far so good, 18 mins left and It appears I have a functional, use-able print. I did adjust the printer settings on the printer itself to increase flow rate to 150%, looks good.

 

Best
