Filament is not "printed" (it is not going out of my hotend )

Hello,
I tried yesterday to print a test piece with my just finished i3 rework, but it seems that i had got a clog, i successfully remove it with a bath of acetone.
Now i just retried the print but it seems that no plastic goes out of my hotend
I removed the filament without problem or resistance, so i am sure it's not a clog because the filament is not clogged (it seems so)
I checked if it was not a jam, and i am pretty sure it is not a jam.

What could it be ?

I printed esun abs
Hotend temp: 225°C
Heatbed temp: 100°C

Thanks in advance

Try hot end at 230'c, tighten your extruder spring

Try to feed filament by hand , when you have reached 225°C. If is is to hard to push, raise temp ( 230-250C is normal for ABS )
When you´ve found a good temp, but the stepper still doesn´t extrude, raise the Vref on the driver a bit.
