3D print leans in Y-axis

I have made a custom 3D printer with RAMPS electronics. I have printed a Benchy (ship) well, but when I try to print anything with teeth (spiral vase), gears (bearing), or a circle (rocket), the Y-axis skip steps in a regular rate giving 70-60…

MOSFET problems!

I ordered a MOSFET module on eBay for my 3D printer and I did not get the one in the picture but I got this: If there is any way I could use this on my Anet A8 could someone tell me how, as it only has one input connector, DC in, and 12 V out.
