I bought long time a go special "eSun cleaning filament", i think its natural nylon. I heat the nozzle to about 260-290 celsius. Then i extruded about 30cm of the cleaning filament. After that i let cool it down to about 60 celsius and i do a cold pull. I don´t need this often, but it really works pretty nice! You get your nozzle absoulutly clean with that method.

About 15 minutes in there was a glob on the print and suddenly the lines were way over extruded, by I dunno, 20%? I set it back to 100% flow and since then its seemed perfect, so maybe it really was a partial clog. I'd not have expected this with the Galaxy Black. Generally I shy away from glitter filaments for this reason but I'd not have expected these types of issues with all prusa stuff. I really suspect that one roll (out of 3 I currently have) might just be bad and is prone to clogging?

Swapped back to the brass nozzle and same filament and gcode it printed just fine. (Hatchbox PETG/Prusament Galaxy Black PETG)

Went into live chat and was told to increase the flow rate to 120% as the ObXidian has different heat characteristics and it does seem to print exactly like the brass nozzle now. But this seems like a huge increase to the needed flow. Is there an issue with my nozzle or is this pretty much expected? If 120% flow (or maybe more temp?) is needed, I'm not seeing it documented anywhere.
