Stepper Motor Issues: Help! Ord Bot

After building my first Ord Bot, I decided to make another one. After assembly I connected the motors and uploaded Marlin firmware onto arduino Mega 2560.


When I try to test in pronterface, connect fine but does not move.

X- moves slightly then vibrates
Y- same as above
Z- no response

LCD display shows no errors.

Please advise!. Do I adjust potentiometers? Power supply reads 12.5V

Is this another wiring issue?

Do all endstops have to be connected?

What am I missing ?
