The title says it.
I bought .6 mm and .8 mm nozzles for my K1C so that I could hopefully print nylon-cf without clogging. Creality Print only offers .4 mm nozzle size for the K1C. I have added a copy of the K1C and tried to change the nozzle sizes but it in not clear I am doing all the right things. It would be nice if creality could offer preset printer choices for the K1C with .6 and .8 nozzle sizes.
