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.
