There’s also a few plugins for Cura with variations on the name TabAntiWarping. I’ve had https://github.com/5axes/TabAntiWarping installed forever but I’m not sure if I’ve ever actually used it in a print. I just took a quick look and there’s a couple others listed in the marketplace now too.
When I first got the printer and was learning I used glue sticks to help with adhesion and just got sick of dealing with the residue and reapplying it - so now I intend on never using them at all if possible. I have 2 of the printers, one just for PLA and has a smooth PEI sheet, the other for PETG/TPU and just the regular textured mat that came with it. I usually don’t need to swap between filament types a bunch so when I’ve got some prints that need TPU it only takes a couple minutes to apply the tape and then I can just leave it on for as long as I want and not think about it. I also use the wide blue tape (can’t remember if it’s 2.5 or 3") so it’s only a couple rows to put on.
Not sure if I’ve ever tried without it, but I cover the standard textured mat with blue painter tape for printing 95A TPU on an Ender 3 Pro. It sticks just fine for printing and haven’t had any issues removing the print after.
I’m guessing it wouldn’t be a valid legal argument, but I liked the thought experiment of claiming that it can’t be piracy if the rights holder is intentionally publicly sharing the content. Like trying to charge trick-or-treaters for theft when they took candy out of the bowl you left out with a “Free!” sign attached.
