-You can create as many Extruder modules as you want, as long as you give them different module names. You can name those modules whatever you want ( as long as you stick to only alphanumerical characters ).+You can create as many Extruder modules as you want (although you may run out of memory and smoothie will no longer boot), as long as you give them different module names. You can name those modules whatever you want ( as long as you stick to only alphanumerical characters ). **NOTE** that the default build of Smoothie only supports 2 extruders (5 axis), if you need 3 extruders you need to compile with  ''​make AXIS=6''​

 This value depends on your stepper motor, the microstepping on your stepper motor drivers, the gear reduction ratio on the extruder assembly if any and the diameter of your hobbed pulley/​bolt. This value depends on your stepper motor, the microstepping on your stepper motor drivers, the gear reduction ratio on the extruder assembly if any and the diameter of your hobbed pulley/​bolt.
