So I just picked up my first 3D printer, a CR-10s Pro V2. I purchased a set of official Creality MK6 nozzles at the same time that I bought the printer, and went to swap out the original nozzle just to try a different size.
First thing I discovered, the nozzle in the unit and the new ones take a different sized wrench, with the original unit being a fair bit bigger. I compared the threads though, and they seem to be the same size and length. However, when I go to thread the “new” nozzle in, it only goes about half the distance that the original did in to the heating element. I had the nozzle heat up to about 200 degrees when I tried to snug the nozzle down. It was definitely tight and would not go further in without applying a ridiculous amount of force.
Once I fired the printer up again, the “new” nozzle prevents the head from coming down far enough for the BL Touch to activate, so the printer work. If I swap back to the original nozzle, all is good again.
Is there something I’m missing here?
