I have this CTC i3 printer; when I print square test prints, as it moves along the Y-axis back to zero (front). It extrudes lines but very thin or none at all.
But opposite direction along the Y axis is 100 %

I can see a couple of problems in your images:
- Your bed is clearly and awfully unleveled. Check on Youtube some manual leveling using a paper.
- Though I think your problems will be solved by correct leveling, if not, check this thread where I explain a little bit about E-step and flow rate calibration. Having these parameters right is crucial for a good first layer.
- I don't know what you are using for layer adhesion but if after doing steps 1 and 2 the problem persists I would heat up a little bit the bed and change the adhesion material (glue, hairspray).

Looking at the first image, it appears that the nozzle is a little too close to the glass build plate. You clearly see that the nozzle scrapes over the glass and filament is deposited on either side of the nozzle. Re-level the bed with a (thicker) piece of paper or with a feeler gauge. Alternatively, increase the height of the nozzle by re-defining the height or add an extra Z raise in the slicer (see question: "How can I add an offset to the first layer to increase clearance?").
