@Bingo for sure you could dissolve the PET, but I fear you will have a hard time trying to dissolve the Carbonfibers

Well, bought this filament today. After a few hard hours I think I got it.
255°C nozzle
70°C bed
0.4mm nozzle diameter
0.2mm First layer
50% fill
Someone already mentioned it, the filament diameter is not what it should. Mine is 1.9mm (No, no moisture, its brand new)
No fans (carbon based materials are very goot heat conductors, they cool down quickly by themselves)
Very slow first layer speed 10mm/s (This one gets even nicer than with PLA)
Printing speed 40mm/s
What to do with the nozzle getting dirty? Dental floss to gently clean it while printing? Maybe a wire of a material attracting it even better than steel?
However I'll share its success or fail.
