Solved Scorched parts of plastic in a print

so I'm printing with a temp of 200 PLA, I just changed colors and am printing a white box (yea, exciting) but I am seeing some scorched burnt colors in some of the plastic. Anyone know what could be causing this? Dirty bits on the print head coming off maybe???

Possibly. I suggest buying some cleaning nylon and using that between color changes.

 

Thanks Mike... But what is cleaning Nylon? Never heard of it....

 

It's a special filament useful for cleaning the nozzle. Look it up under cleaning nylon filament.

Printed solid sells it: https://www.printedsolid.com/shop/175-3/extruder-cleaning-filament/

 

thanks for that, just ordered some! Love the tips I get here!
