I am making a very small 3d printer using 2byj-48 stepper motors running at 12 volts. When homing the Y axis the motor pauses at I think random intervals and draws more than 3 A of current(the X axis motor only draws 1.26A). Does anybody know what is the problem?

What is the mass of the Y carriage? Compared to the X carriage? Usually the issue. Too much mass = erratic movement. You could try turning down the acceleration.

EDIT: Include the belt mass as well.

You could try swapping the motors to make sure that the Y motor isn't defective.
