The most versatile and best looking filament you can print
HTPET+ is an amazing filament. It is to HTPLA what HTPLA is to normal PLA. It feels nearly as stiff as PLA, and stiffer than HTPLA, but like HTPLA it's not brittle and it can stand higher temperatures than either. Layer adhesion is excellent. It's also gorgeous. I printed on glass at 70C with either Magigoo or 3DGloop. Both helped a bit, but to really get HTPET+ to stick and not peel upward on glass I used a 6mm brim, turned off the fan for the first 15 layers, upped the extrusion width to 200% and increased the flow on the first layer to 122% in SuperSlicer. If you're printing on PEI or another surface you might have less trouble, but this worked for glass. Use an interface layer like Magigoo with glass and removing the print before the glass fully cools, I usually waited till around 50C and didn't have any issues removing the prints with a scraper. For the hotend I printed with an all metal hotend at 285C and didn't have any issues. HTPET+ does tend to string a bit but it's usually just tiny wisps. I tried lowering the temperature down to 270C and got a jam, so I'd stay north of 275C. I did notice if the print slowed down on small and quick layers the extruded filament would turn milky. I would recommend turning up the minimum print speed on fast layers and on those layers set max fan to 100%. As far as cooling, above the first 15-20 layers where I kept it off to prevent peeling I kept the fan at 60%(100% on bridges). Bridges and overhangs printed beautifully.
