Manual Control: nothing moving

I have everything set up and am at Pre-Print Testing stage (p18). When I click on Manual Control in Repetier-Host and click on the x,y or z arrows nothing happens with the printer. I've tried shutting down the printer/remove/reconnect usb etc. Repetier is connecting with the printer, and I can hear a very low humming when I press the arrows, but nothing moves. All of the packaging is removed, so nothing should be anchored.

Also the blue space at the top reads: Idle. Voltage selector is correct.

Printbed is working, when I turn it on.
Fan makes a whining noise when turned on, but I don't feel any airflow.

When I click on the arrows an error message shows at the bottom that reads:
echo:endstops hit Z:0.00 when I click the Z arrow
echo:endstops hit X:0.00 when I click the X arrow etc.

Any suggestions?

Thanks!

 

i think you should home everything before you try the arrows, they didn't work with me until i Homed them

 

Thanks, homing solved the problem, they mention it in the video but not the manual.
