@vladimir.minkov Thanks very much for posting your settings. Which make and model of PETG are you using (or from which those settings were derived)? It would be best if people post that info as well whenever they post their known good settings, because I’m pretty sure there’s an interesting story yet to be told regarding different PETG filaments on the market (essentially raw PETG but with maybe very different “additives”) and how they play on this machine. For instance, when this thread started, BBL didn’t yet have a PETG filament that it was selling, and it was even quite a while longer before it had one to sell–and it certainly wasn’t for lack of demand.
