Hyper Petg-CF Print settings for K2 Plus w/ Microswiss Hotend 0.6mm nozzle

I have been trying hard to get good prints out of the Hyper Petg-CF with a 0.6mm nozzle on a k2 Plus.

Printer upgrades:

-Microswiss Hotend with the CM2 nozzle.

-All metal extruder feed gears

-All metal extruder drive gear

-High quality PTFE tube to replace the extruder feed tube.

The extruder gears and tube swap definitely helped with more consistent feed and less clogging with the abrasive nature of the filament.

I have been struggling with getting it to print at a high quality standard however. I’ve tried all different sorts of setting and ran through the print calibrations on creality print several times. It seems that once the information from the calibration test are put into the slicer there is still some form of issue with getting bridges and overhangs to really take shape. I’ve tried slowing them down to 20-25 with fans at 50-80 percent and still struggling. Can someone share their filament settings with me to help get this headache taken care of ?

Did you try to dry your filament? With my K2 Pro with just the stock nozzle and extruder PETF CF prints pretty good with the stock profile…

Yes. I’ve dried it and i print directly from the space Pi. I was able to get a decent prints from the stock hotend and nozzle, however, I was getting clogging and it would occasionally heat soak causing jamming. That’s why I made the switch to the Microswiss and 0.6 nozzle. I’ve not had those issue since.

It’s just a matter of now no matter what I do, it seems surface finish is just poor, and the first layer of bridge are sagging and just rigid enough to get a quality bridge.

I did order a obxidian 0.4 nozzle. And I do have a CM2 0.4 nozzle for the microswiss.. I’m not sure if the issue would be more easily resolved going back to the .4 nozzle and making PA, Flow, and MVF changes then use the preset profile for the hyper petg-cf Creality offers.

Mmm, frustrating indeed.
What i would do is try to get back to known good setup, with the stock nozzle you should be able to get good results. The more expensive nozzles should be more durable and probably higher flow,

I finally got it ! Boy was it a headache. I went into the fluidd interface and grabbed the auto calibration parameters, Input it into the custom filament profile. I made a few speed tweaks and upped the volumetric limit and it prints beautifully now. I am going to update the originally post with my parameters and hopefully it’ll help someone with the same set up in the future.
