Hi Pog,
My opinion ........
Can the 5volt power supply come from one of the drivers?
No - you need a 5 Volt supply connected to +5 and GND on the BoB.
What DC voltage are you using for your drivers ??
I have DIR+ (+5V) connected to GND on the BOB and PUL+ (+5V) connected to +5v on the board. Is that correct?
No - these should be left unconnected.
theres ENBL+ (+5V) and ENBL- (ENB) with no connections on the driver.
This has yet to be established but leave unconnected for now.
Output signals is where I get lost, I have no idea what I have to do there, what pins are they? port #1 but pin?..
Open Mach / Click on Config (in menu bar) / Click on Ports & Pins / Click on tab Motor Outputs / Enter Pin# here and select active low.
Tweakie.
