Well, I do have to say this sucks. The big sprocket/gear in the extruder sheared on me mid print. Kind of wish Creality made the entire gear out of metal instead of half-and-half. But I have the new exterior kit ordered on Amazon will be here tomorrow. Kind of disappointing that after only a total of four days of printing time, my profile says this happens. Kind of wish we were able to buy individual parts separately but that’s not the way it goes apparently.
