Motors problem

Hello everyone

I'm building a 3D Printer, everything looks pretty good, but when I tried to run it the motors just aren't moving, what is the problem?

note: the motors easy to turn by hand when the power is off, and difficult to turn when the power is on.

using NEMA 17 stepper motor - 1.8 ° - 1.7A.

This can be many things..

1) you have to have the correct MOTHERBOARD set in configuration.h
2) you need you stepper driver type set in firmware
3) you need working endstops (check with M119)
4) you need the vref on the stepper driver set to match your stepper motors (DO NOT USE A METAL SCREWDRIVER!!!! this nearly always kills the stepper driver)
5) you need 12v on the 12v 5amp power plug
6) you need 3 micro stepping jumpers installed under each stepper driver.
7) you need sane steps/mm settings in firmware
8) you need sane max feed rates in firmware.

and this is all presuming its not binding mechanically

oh I forgot to put 3 micro stepping jumpers under stepper driver.
thank you sir.
