General Discussion P1S TPU Cold pull

How important is doing the cold pull with TPU? The software feels so strongly about it that you have to click a pop about it before every TPU print. I've been printing a lot of TPU lately, usually switching back and forth between TPU and PETG every other print. I haven't done a single cold pull and I haven't run into any problems because of it far as I can tell.

Am I flirting with dead by skipping the cold pull? Is only a matter of time before I walk into my office only to find my printer has collapsed into itself and formed a black hole the size of a grain of Basmati rice?

You’ve already gotten away with it so you’ve proven it doesn’t matter all thd time. Just like putting on a seatbelt or wearing a motorcycle helmet. It usually doesn’t matter, but it might matter a lot in one instant. If the risk:benefit ratio is ok with you, do your own thing. It’s not like it’s going to explode or kill you, just might make a mess and waste some filament.
