I finally got some time to get back on my picker machine build
Here's what I need to do
I am setting up a dual axis Y and open drain is not working for me with my smoothie board
My smoothie board motor driver outputs 3.3 volts
My TB6600 stepper driver requires 5 volts
So I purchased a few Logic leveler boards to step up the 3.3v to 5v
I have never used them before and I want to make sure I am hooking them up properly
Looks like I have to supply +5vdc and +3.3vdc to the logic boards which I can get from my smoothie board
Is the attached hookup diagram correct?
This is what it says on the smoothie dual motor page regarding a TB6600

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 ).
