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.
