If your printer allows you to control the extruder that the point it has stopped for a filament change then by all means go ahead and use that approach. The less you have to handle the printhead the better as there's always a risk that you'll knock it out of alignment and spoil the print.
Excellent tutorial video I have just started with 3D printing and this helped a great amount, but you did not explain how to have the firmware recognize the M600 in the G-code if it is not. This is done by opening up Marlin and go to configuration H and under the Edit tab the find function for M600 then un-commenting //#define FILAMENT_RUNOUT_SENSOR saving and uploading this to you printer.
instead of pushing the new filament though the extruder, could you use the LCD panel commands, or a control program on the PC (cura, repetier, or pronterface) to extrude say 50mm of filament?
There's a good chance you'll be able to use this technique on a Wanhao Duplicator i3. The critical requirement is that it supports some form of filament change command in its dialect of GCODE. I'd recommend obtaining a list of supported GCODE commands from Wanhao to let you confirm this. In the version of Marlin firmware running on my Prusa i3 derived printers the command is "M600" but it varies between printers.
thank you so much for this video

Great tutorial! Straight to the point and detailed. Is this possible with a Wanhao Duplicator i3? It is similar to the Prusa i3. Thanks!
