First new nozzle
First, I'm a hack. I print for fun and utility. I make stupid stuff for around the house, and functional parts. I don't sell things, or run a print farm, I just print for myself. My first printer was a MK3s from about 5 years ago. I ran it happily until I decided to upgrade to a Core One. Which I upgraded to a + for no real reason. So I really only know the basics. I have only ever, printed PETG. However I now want to print some stronger parts so I want to try PC-CF or other carbon fiber variants. But I do not want to have to change nozzles all the time. I want a "fire and forget" nozzle. So reading about them here, I decided on either a Diamondback .4 or an Obxidian 500 HF .4 - which I ordered and now own one of each. I finally flipped a coin today as to which I'd try first and went with the DB. Installed it, and printed a benchy. Came out fine. After reading about how the Diamondback needs to have nozzle temps lowered by 5-10 or so, looking at the benchy which I printed at the default .20 structural (not high flow) profile, I am not sure if I need to adjust temps? It looks fine to me.
So I printed a temperature tower, but honestly I don't know what I'm looking for. Seems like there are maybe some bottom layer issues at the bridges with lower temps, and maybe a little stringing at 260, but what am I really looking for here? To me, 245 or 250 look best. I used the Prusament Galaxy Black PETG I had loaded, but am thinking it probably wasn't the best choice due to the "glitter" - maybe I should redo it using plain black or grey?
Thoughts? Any reason to try the Obxidian? Or leave it alone and print...?
