Dramatic failure of calibration print
The failure you are faicing is underextrusion. Underextrusion can have several reasons. Among the three most common I encountered in my printers:


The nozzle could be clogged, hindering flow (Very crushy, squishy prints after it worked fine before)


Dissemble the filament path till you can push an acupuncture needle through the hotend, heat it, press out all filament, reassemble. 

The extruder might be skipping steps or shredding filament


check if it is just not gripping the filament, not turning at all or clicking.
real Troubleshooting might be needed

The g-code might have a bad setup for the filament you are using - try upping the higher extrusion multiplier/flow rate and print at least 2 walls!
