    Yeah, my major qualm about 3D printing is that all of the plastics I would like to use are higher heat than any entry level printers.

        PETG is a good argument against my statement, but it still prints at a temperature between 220 and 260 C. PLA prints at 180 to 220 C.

        PETG is a higher temperature plastic than PLA, and a lot of cheap (below $200) printers don’t work well with it.

          Old Ender 3s and the like work just fine with PETG. Not sure where you got the impression they don’t.

          There’s nothing special about printing PETG that requires a big change over PLA. Printers have been hitting those temps since the rep rap days.

            Personal experiences with a cheap sovol that turned itself off when the temperatures went up during a long print.

              It sounds like it may have been reaching a thermal shutoff point and killing itself. Maybe the temp you were aiming for was close to the limit, and slight variations caused it to go over and “save” itself.

              The only thing that might keep a printer that prints PLA well from printing PETG well is if it’s an old printer without a heated bed. Save for that (and potentially faulty hardware or miscalibrated settings), there’s not really anything that “can’t” print PETG.

              I actually have some PLA+ rolls that print at higher speeds temps than my PETG rolls 🤷🏾‍♂️

                I’m sorry but that’s incorrect. All of that. Your guesses were wrong. Except it is absolutely a sensor telling the machine to turn off, that part is right.

                  You seem incredibly confident in your diagnosis for someone who can’t get a very common filament to work on printers that have been using it for years. Care to elaborate more than, “you’re completely wrong, except for where you’re right”? What was causing the problem?
