In this picture you see the very bottom of the extruder, where the icing tip pokes through the hole in the bottom piece of wood.
If it’s not broke, don’t fix it! Method 1: Automated Tuning using GCODE. The most simple way of performing a PID Tune is to “print” a gcode file that executes all of the commands automatically. Note: These files are for the Duplicator i3 and are reported to NOT work with the i3 Plus.

I can upload my marlin and repetier firmware if necessary.

So I'm not sure why during a print, it won't extrude anything. I'm currently running ...
