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 ).
