Are you sure the nozzle isn't blocked?

Do you have the fan attached to the heatsink and powered up?

If you didn't, I'd say you're getting heat creep and the filament is expanding too high in the extruder. What temperature setting are you using?

The knocking noise is probably the extruder stalling and restarting. You could check motor current.
I'd say take careful note of the nozzle assembly instructions. It's important that the nozzle tightens against the heatbreak and not the heater block. also the ptfe tube needs to push up tight. Check instructions about a 'chamfer' on the end of it.
