Sounds like a thermal runaway where a temperature changed too quickly and the code interpreted that as a fire or risk of fire and shut down. A lot of times that can be helped with a silicone sock and a PID tuning. Another thing is the ceramic heater core is going bad and it can’t keep a stable temp above a point. Heater cores are cheap and easy to change. The heater core is considered a consumable part and usually comes in multiple packs.
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?
It is, but you’re being incredibly hostile (and vaguely xenophobic) towards someone who was literally just trying to chat about an issue you were having with a product you purchased and were disappointed in.
I’m still curious as to what you determined the problem to be with your printer, but I’m assuming you never figured it out, threw it in a closet, and now bitch in 3d printing communities about how bad their hobby is.
Ive definitely gone through periods of hating petg just because it’s sticky and in my experience any amount of over extrusion results in it building up on the nozzle. It sounds like something may have been wrong with your printer. Shutting down from the hotend being too hot is odd unless that printer specifically has a low max temp or the hotend was doing something to trigger a shutdown. I have 2 voron printers now but I printed all of the parts for the first one out of petg on an ender 3 V2 without issue.
No it printed PLA just fine. It shut itself off while printing PETG, before or after successful PLA prints, because even if I manually set the temperature it does not handle heat.
I don’t care about your printer, I didn’t ask, I’m sharing my experiences. You can’t explain things in a way that invalidates my experiences.
I’m not trying to invalidate anything of your experiences . I mentioned my printers as an example of printing a ton of petg on a cheap printer. I have no experience with your printer specifically, I was just trying to say that it is possible to print petg on a cheap printer but undoubtedly there are similar stories as yours on the same printer I had success with.
I also didn’t mean that your printer was broken or couldn’t print anything, but if the petg temp was right on the edge of the max set in firmware and the hot end drifts too much, it’s going to trigger a shutdown. The drift in temp could be bad PID tuning or even a lose connection. If that were the case you would be able to print PLA just fine because the drift wouldn’t exceed the max temp and trigger a shutdown.
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.

Your native language must not be English. Goodbye, friend.
