PET-CF config

I bought a spool of Siraya Tech PET-CF. On my Core One there isn’t a PET choice when loading filament. What do I do?

RE:

You create one. I'm not in front of my printer right now but you can go to the filament user presets screen on the printer and simply add it. I can give you exact instructions later. 

What nozzle do you plan to use with it? My advice is to use a hardened 0.6mm and not high flow. 

Let me know and I'll attach a calibrated profile for it. Just be aware that PET-CF is at the upper limit of what can be successfully printed on the Core One. Meaning you'll need to run the nozzle at 290° but PET-CF likes 300 or 310

I have a 0.6mm hardened nozzle (not HF) that I can use.

I'll send you a profile shortly. I haven't actually printed this filament on a Core One, I use my H2D for that. I have printed Fiberon PET-GF on a Core One which has a lower temperature requirement.

Just be aware that on a Core One with a 290° limit, you are at the lower end of the temperature range so there might be layer adhesion issues. Also, this filament is very brittle.

Try this one. You might need to lower the max volumetric flow slightly since this is calibrated for a 0.6mm Diamondback nozzle.
