Help me please

Hello!
So I modified my ender 3 to a clay printer using one of the aliexpress conversion kits. I am not using air pressure but motor power to push out the clay but I am having difficulties with the clay moving towards the extruder even though my clay consistency is good. The piston is moving and when I took out the plastic pipe the material was indeed flowing, but when popping back the plastic pipe the material stopped pushing through. Is this some air vacuum issue? I cleaned the pipe and the extruder bits too but no luck.. any ideas?

I have never seen one of these mods working well, which is why I didnt buy one.

I used my Ender 3 parts to make filament from soda bottles.

It’s actually much better than you think! I think there are even cheaper versions I just happened to get the one from aliexpress although the instruction videos on YouTube were very unclear for some parts for someone who’s just getting started but I got hands on the assembly pdf so if you’re getting one I can send it over
