Dual Z in smoothieware isn't too hard once you find the near impossible to find clues. LOL
Herculien's machine gave me the clues, as his has a dual z.

First, Copy your config.txt off to the side or add a 1 to the copy's filename, so you have an untouched/unchanged reference.
There's 3 jumpers next to the E1 driver socket [JM6]. Connect them with 3 jumpers. This locks both E sockets in step with each other.
Then you swap numbers in the config.txt, the E1 pin numbers go in the Z part of the config, and Z pin numbers into the E1 part.
Your extruder motor will plug into the Z socket, and your two Z motors will plug into the two E sockets.
If your config.txt has the section for a second extruder, comment all those lines out. Mentioning the E2 pins anywhere will cause problems.
No need to increase current for Z, both are set to what you set for Z in config.txt (aka a single motors current needs).

As for the 2660's, I wasn't that successful with them. I use the 6128's.

Please note, if your external driver requires 5V, that Smoothieboard only provides 3.3v on it's output pins.
Two solutions to this : either use a level shifter or use the Smoothieboard's pins as Open-Drain
( ie linking to ground instead of linking to 3.3v, when closed ), and wire accordingly.

Since TB6600 uses 5V signals and Smoothie is 3.3V we should either use TTL converters or open-drain (as mentioned before).
My setup uses open-drain with 5V taken from the board ( signals are connected to “-” pins, 5V is to all “+” pins ).
