I got to give Bambu some brownie points and I don’t make a habit of this but my TPU prints turned out so well on my A1 that I could have passed out. One or two spider web sized strings was absolutely not what I was expecting at all. I was anticipating the worst string goober ever made. You Go! Bambu! & Thank You.
I use my A1Mini for TPU printing. Mostly due to the silly implementation of TPU on the H-Series printers (which are my other printers). That little Mini kicks butt with TPU. Outstanding results.
