Chack your breakout borad as follows.
apply 5v to the supply pin. Check this supplies both the computer side of the board and the mill side.
connect each output you want to use, say 2, 3, 4, 5, 6, 7 to a led and each led via a 220 resistor to
a rail connected to +5v
then add a wire to the ground terminal.
use this to touch pins 2 3 4 5 6 7 in turn and see if it turns the led off
For mach 3 go to the config window
go to portsd and pins
set port 1 to enable set port 2 to disable
enable output signals 1 2 3 4 5 6 to enable
set port to 1 for these signals
for output set pin
1 2
2 3
3 4
4 5
5 6
6 7
for pins 2 to 7 set active low
click apply and end?
you will have to go to congig again then select motor outputs
set enabkle step pin dir pin step pot dir port
x yes 2 3 1 1
y yes 4 5 1 1
z yes 6 7 1 1
click apply and end
connect board to computer with leds still attached
leds should be on (or off?)
go back to ports and pins and toggle for each pin the active low
doing this should change the state of the led for that pin
