gr5 already posted an answer to the first issue in another thread where I posted the first image. Here it is:
But none of this is what you want to know!!
What is wrong with your print???
I'm not sure.
1) Was this printed by itself or with other objects at the same time? If the answer is "other objects" then almost guaranteed that is "stringing". You can verify by looking at the gcode view in Cura and there should be a blue line right at the exact same location of each blob. You can fix this by printing one object at a time. There are other ways to fix stringing but the best is method in this case is to print one object at a time.
2) It could possibly also be caused by over extrusion or over pressure - sometimes the pressure is too high and the UM keeps printing just fine until suddenly it all leaks out in a burst/blob. This could be caused by a bad Z movement - maybe it is sticking and some layers are less than desired so there is less space for plastic and over pressure (over extrusion).
3) It could be infill. This also can be checked by looking at the layer view and see if each blob lines up perfectly with the infill pattern. Even better, print it again, look at it when it is half way through and see if the blobs line up with the infill. If this is your problem, increase the shell thickness to .8 or 1.2mm to prevent the infill from reaching past the outer skin. This "extruding infill" is a problem with the latest cura (steam engine). I have some details on it here:

Looks like a combination of slight over-extrusion, a slight amount of oozing from printing slower and hotter than you need to, and maybe a slightly too low amount of retraction.
It could also be too slow of a travel speed - make sure that's at 150 or higher.
