Profiles for printing with PC

Can you please share some profiles for printing with PC that I can use as a starting point for tweaking?
I am currently trying to print Polymaker PC MAX with quite bad results.
I tried using the supplied PLA-N profile,disabling fan, increasing temp to 250 degrees and bed temp to 110, and the results are quite bad. The biggest problem is that the nozzle starts to pick up plastic around it and this plastic interacts with the part being printed. Also the surface of the layers is not smooth. I tried different temps, from 230 to 260 ( polymaker recommends 250-270 ) and also different bed temps, with no success.

Thank you for contacting us.

Regarding your question, please check if the nozzle is well calibrated, or if it is too close to the printing bed.
In addition you can try to change the flow rate in Cura: "print settings -> material -> flow", reducing its value.

Sorry I can't help with your problem, and I know you said you disabled the fan. I just wanted to mention that it looks like your fan installed the wrong way. It should have the arrow ponting down. Just an observation, unless you have it that way for a reason?
