I’ve got a half roll of PA6-CF on the way, figured I’d ask some general questions on calibration and printability before I get started as this will be my first time printing PA6-CF. If it helps, I’m using 300blkFDE’s settings on an Elegoo Centauri Carbon, planning on drying the filament first in a toaster oven and using a Sunlu S2 filament dryer while printing.
What calibration prints are considered essential when first printing PA6-CF? Also, what issues in those calibration prints should I be looking out for (dimensional accuracy, wet filament, etc)?
Is Sunlu PA6-CF comparable to other brands like Polymaker, and do 300blkFDE’s settings translate to Sunlu? Are there any changes I should make to settings?
Are there any general things I should keep in mind while printing and annealing? I’m planning on printing a few rimfire cans (probably FTN.5 rimfire and rimfire flow) once I get my Form 1s submitted and approved.


I just made a post with some Sunlu pa6-cf. Make sure and dry it good as in like 80-90c for 24-48hrs. Use my settings and I changed my flow rate to 1.1 I have also found that it like the temp closer to 280c vs 300c which will be perfect for your printer. What nozzle size are you going to be using? I ask this because I did run into a few clogs with a .4 nozzle so I switched and used a .6 nozzle with my all my line widths set to .5 and a .12 layer height.
