Help! What happened?

Can I reset the entire software?  Maybe the mod can move this post to here...

Alrighty, link got (immediately) integrated.  Nice forum engine.

The best way to reset Cura is to go to "Help -> Show configuration folder". Then close Cura, and remove all the files from the configuration folder that opened, but leave the empty folder in place.  Then restart Cura.

Problem discovered and solved!

Thanks for all the help guys, but check this out...

After sending a couple kilograms of filament through my first nozzle (I did not really think they wore out that fast), I guess it gave up the ghost all at once.  The new one has a much pointy-er nose on it and is spewing hot plastic like a finely controlled champ.

Wear also depends a lot on what materials you print. Filled materials (metal fill, sand/stone, carbon fiber, glow in the dark,...) tend to wear out brass nozzles very quickly. Even plain white wears out nozzles, more than other colors, I guess because some are filled with chalk to make it opaque white.

Well you are certainly right.  My new, less than a week old nozzle is no longer pointy nosed.  It is not 3mm in diameter like the first one was when it failed, but it is flattening out after doing a few glow-in-the-dark jobs.  The stuff I have is like emory particles on a strand.  I thought that the nose doesn't touch as it lays out the next layer, but apparently it drags as it builds?  I set my nose in bed leveling at about 0.11 mm on the bed center and get excellent results from a new nozzle, but I started noticing quality changes after a few print jobs and sure enough, the nozzle is starting to flatten.  I am going to have to get one of those tungsten nozzles I saw on Amazon.  Are they all pretty much standardized or are they machine specific?  I would think there are probably two or three main types, but I haven't looked yet.  That's next.  Just wanted to update you and confirm your assessments.

Yes, you really need a hardened nozzle for glow-in-the-dark: it seems it contains very hard crystals, harder than brass. But I don't know which type of nozzle is suitable, no experience with that. Maybe hardened steel might do, maybe not and it needs to be a ruby? Try finding the hardness of the particles, and nozzles?
