Hi Billy,
couple of issues, you are using outputs 16 and 17 for X step and dir pins and yet you are using pin 16 as Output#1.
May I suggest using pins 2 and 3 as X step and dir, will require you wire your driver to the new pin locations.
You have five enable outputs, Enable1 thru 5, all attached to the same pin. Its probable they will fight. Just use one output for one pin and
connect that pin to all your drivers enable terminal.
Retain Enable1 as active low, disable Enable2 thru 5.
