I was thinking about getting the Kobra 3 v2 combo but i want to be able to print carbon fiber reinforced like pla or petg. Does anyone have any hotend and nozzle recommendations because I saw that's what I should get. I was thinking about getting a Neptune 4 either Pro or Plus because supposedly you only need a Hardened Steel Nozzle but then I saw the Kobra 3 V2 and saw it wasn't only a multi-color but with an All-Metal hotend and a Hardened Steel Nozzle, it too could print carbon fiber reinforced filaments.
