    Why do you post this in a "Repetier firmware" Forum? :) This seems not to be related to firmware issues and should be discussed in a more appropriate forum. 

    You may google for hot end jams for instance. Typically those hotends are pretty cheap and might be improved by some rework (i.e. drilling through it, cleaning it, deburring). There are a lot of youtube videos on that topic.

    Jamming happens if your hot area gets too big. So lower temperature, improve cooling or google for common sultions fot that exact extruder. Each one has it's pros and cons.
