It looks like operation z-wobble removal is a success! I printed out a tall, thin print with what’s left of my white to test the fix. http://www.thingiverse.com/thing:28690
As you can see, it’s MUCH better than it used to be. I had some issues that I think are thermal in nature as there are a few layers that didn’t bond well.
I blame http://www.thingiverse.com/thing:20147 for the dramatic improvement on my printer.
There was a week layer. Not sure if the printer z-lifted and didn’t settle back down or if I had a cool layer and it didn’t bond well.
