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.

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 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 🤷🏾‍♂️
