Extruders

[AutoWiz]

The gear reduction will shine more at slower speeds and also in more precise retraction control. because it is 3x as many steps to travel the same distance. It also shines when you start dropping layer height and / or nozzle sizes and the filament is always moving slow. The gear reduction lets the stepper motor spin at a faster rate which is nice when it is barely crawling along. As far as experience with extruders goes ya I have a little under my belt. In fact of the 4 printers I own 3 are dedicated to never ending upgrades, mods, and conversions for the sake of collecting knowledge. Here is one printer of mine that has seen 4 different extruders: http://3dprintboard.com/showthread.p...Mixing-Printer

That printer runs a titan extruder now. Here is how I have my titan configured..
