I am new to 3d printing and have a Prusa I3. I am to the point where I can print but the extruder stops extruding filament even though the motor is still turning.

I have my spare mk8 on the workbench so I took a quick photo of how it would usually look, minus the heatsink and fan

The thing that strikes me about your photo is the lack of pre-load on the spring. It looks like you are missing the second screw in the top of the spring that the adjustment screw bears against to compress the spring. That would explain the lack of force to grip the filament. The heatbreak might be playing a part, but until we get to the point where it's all but impossible to stop the filament with your fingers we have more basic problems
By the way, I don't see anything fundamentally wrong with that design - it looks like a good solid piece of kit and I'm sure we'll get it working.
