Cleaning nozzles?

Postby tmccafferty » Fri May 24, 2013 3:39 am

I've seen several posts where people refer to cleaning their nozzles. Not trying to sound dumb, but do you do that? Since I switched to a j- head, I have had no plugging so don't understand when/why you clean the nozzle.

However, my prints have started to suffer from what seems to be starving a bit at the nozzle. All layers aren't fully joined and top surface is clearly starved. I reduced the filament diameter. Bit but didn't help. Nothing has changed. Not even the material.

Kind of wondering if nozzles need periodic cleaning.
