I've seen a few people speak about replacing extruder parts on the CR-10 smart to get more reliable prints, but I can't seem to nail down exactly which parts work with the printer.

Will any MK8 parts work, or do I have to find something specifically? I've seen all-metal extruder sets on Amazon and elsewhere, but I want to make sure I'm grabbing the right part before I dive in.

I haven't been having issues with mine so far, but I'd like to get ahead of any issues I might come upon in the future. Specifically, I'm looking for an upgrade to the extruder, which I've heard isn't super reliable - but I'm open to any upgrades that other CR-10 smart owners have done to get the best prints from their machine.

Right now, I'm on a very lightly modded CR-10 Smart - all I've done is connect an Octoprint and disconnect the onboard wifi module.
