Hey all,

TL/DR: How long should a nozzle last, and how do you optimize its lifespan?

I recently had my MK4s working absolutely fine, but just suddenly it became unable to print. Like it’s fine, then the next attempt fails and I can’t stop the clog detection.

So I probably could have cold pulled. I probably could have done more preventative maintenance, but TBH, the MK4S is so solid I just don’t think about it. Plus I’m like “I just upgraded this,” but checked history and it’s been over 18 months. So I figured

I replaced the nozzle and the print that kept failing now printed better than ever.

So anyway, I’m happy, I’m not complaining. But what are people doing to maximize lifespan and what to people think is the “time to replace”schedule (at yeast in terms of printing hours)
