Here she's working again.

This is the finished product I've been trying to print since May. This is unbelievably nice to have my printer capable again.

This is what started it. I just wanted a different nozzle size. Aw, SNAP!

I was trying to switch back from a .6mm nozzle back to a .4mm nozzle. Apparently because this is a volcano nozzle, they don't like going back out.

My old heat block takes a dip. In carburetor dip.

Looks like I'll be using my old heat block. My nice new one just isn't letting go of the nozzle. The problem: my old heat block was encrusted with burnt plastic. Y'know what's great at eating up not-metals? Carburetor dip.

Simply putting my old heater block back on didn't work. Z axis wouldn't tram to the print bed. Hm.

I didn't get a picture of the mess it made to my print bed. Here, I have decided to take Andy's advice and put in a set screw. This is where I am deciding to put it. Look. There's a really great spot behind the cooling fan that I just unmounted.

There's a pesky mounting plate in my way. I will remove a cylinder through the plate with my drill.

Here's the pilot hole. It's best to use the pilot hole to make sure the final hole is where it ought to be.

There's a nice line. Now my set screw has a home.

I made sure to tap it with a M4x0.7. Everything lines up, I've found a screw. Let's put it back together.

Level. Tram. Level. Tram.

I had to tram/level my print bed 3 times to be certain it was right. Turns out that I was putting a little bit of pressure on the print bed with my hand while I was trying to set it. (This time. Oops.)

I finally printed the last part to the child's bedroom. This is a jumbo rocker plate to fit a USB/outlet and a nightlight.
