Unknown problem with printing (with photos)

Hi everyone,
I was trying to print some part with my prude i3 p802m but for some reason I get this:

Does anyone have an idea what is the problem?
I have already printed stuff with that printer before.. And the curves are happening only on the left side of the bed.. And keep happening after 3 tries..

Thanks

is the bed level? , layer height correct? also check your hobbled gear clean it also imake sure dler set correctly with enough force to push filament through but not too tight it stalls it
