Homing not working

Hello,

This is my first build... I am building a Rostock with a Ramps 1.4 and arduino mega. I have the 3 XYZ steppers plugged in correctly, the drivers are working. When I go in on the LCD and choose auto home, the motors just vibrate and don't move, they do this under no load. Does anyone know a solution for this problem?

Thank you

Your stepper motor drivers aren't supplying enough current. See the motor section on the Calibration page of the wiki.

I'm getting my first delta printer up and running as well, and have had some success following this guide to get the print platform moving properly, and that calibration document on the wiki for tuning of the other parts unrelated to head movement.

If you choose to move each axis alone, they are moving? For example if you try to move only x axis?? 90% you haven't enough current but I had face a similar problem with homing, but when I changed my firmware it worked correctly.

Yes, when I move each axis individually, they move correctly.
