Looks like a serious lack of adhesion to me. Without knowing the material you're using or the temperature you're printing at, I couldn't even take a guess as to the cause. Please save a factory file and upload it here in addition to telling us what the material is.
I had a similar issue. I increased the extruder temp, slowed down the default print speed, and increased the extrusion multiplier. About 5 % at a time. I’m very new to this, I’m not sure which adjustment fixed the problem. Check out the print quality under the support section of this website, its helped me a lot.
