How can I extrude without heating my hotend?

[BoneHawk1]

I have A CR-10 and have recently installed a Paste Extruder mod. It all works great except for the fact that I have to heat my detached hotend for it to work.

Does anybody know a workaround for this?

3 solutions.

1. Add Gcode “M302 S0” in your starting gcode.
2. Modify your configure.h in Marlin firmware as followed.
   //#define PREVENT_COLD_EXTRUSION
   #define EXTRUDE_MINTEMP 0
3. Installed a resistor(I used 270ohms for 224C) where the hotend sensor plugging in to.
