I am currently in the last steps of building my Shapeoko 3 Sparkfun Edition. I have connected all the motors but I think the Y-axis motors are not connected correct. When I switch the controller on, the “Direction Y” LED on the Stepoko board does not light up. And if I try to move the Y-axis, the motors seem to lock each other and make a bad sound.
I did test the different coils on the two motors (red/blue and green/black where a coil on each motor) and connected red of motor one to blue of motor 2 and vice versa and green of motor 1 to black of motor 2 and vice versa.
When connecting these pairs to the A+/A- and B+/B- terminals on the board, I connected them so that both red/blue pairs got on the B terminals and the green/black pairs got on the A terminals. Is this not correct? Do I need to change them?
What causes the “Direction Y” LED to not light up?
