Geeetech

hi
i have a new geeetech i3 and i assembled it correctly and everything is working correctly except there is no filament coming out from the nozzle ,
first i think it was the extruder motor and the heat but i use 250c for the abs and i tested the motor with out the filament and with the filament without the nozzle and it works fine.
second i dissembled the extruder and heated it and try to push the filament with my hand and nothing goes out as you seen in the picture attached note : temp:250 , filament : 1.75 ABs-b from geeetech , extruder : 1.75 to 0.3
so please help me what i can do i didn't run it once

The hot end is block. Please use a thin copper wire to clear it.

i used and cleared it many times and nothing

When you take the hot end apart like this, can you see any light through the hole?

No , I don't.

Do you have a needle? Please use a needle to clean the hot end when heating.

I am traveling abroad ,I'll try when i come back

ok now there is something goes out from the nozzle but when i tried to print something nothing appear usable and flow is slow and didn't stick to the bed .

please can u send me a test file to print
