CTC i3 Y-axis thin / no filament deposition 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&nbsp;%
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).
