not extruding while printing

[changastyle]

Hello, I am having a problem with mi new Delta G2S:

When I send something to print, the filament doesn't move not even 1 mm

But when I handle by manually (In the repetier Host , in tab Control Manual) the filaments extrude well.

1 - This is the video of the printer "printing" and filament doesnt move:

2 - This is the video of Manual Control, extruding well:

What I should do? the printer is brand new, so I still could not print.

I have downloaded the firmware and G2s.ini from geetech website, and didnt change nothing.

Hi,Does the extruder motor work when printing?Please take off the fan and take a video which gives the motor gear a shot.

When I'm printing this is the movement without the fan:

Hi,according to this video,I think you need to increase the voltage of extruder's A4988.Please check this post for more detail:http://www.geeetech.com/forum/viewtopic ... 19&t=17097.
