It's losing X axis and Y axis coordinates during printing, the print object get dislocated.
What happens is, it prints half, or an fair amount amount and then goes to some near points and at this new position it keeps printing like nothing happened.
Everything on hardware is fine. The belts are fully tight, the current of the motor is adjusted as it should, the axes of the motors are free, the temperature of the motor during work is ok, the maximum velocity is 360 mm per minute and even this still happening. I look up this solves http://wiki.solidoodle.com/fix-axis-shifting and none of them worked for me.
