Newbie here.
I bought a kit on ebay just like this one :violin: ...
Wholesale cnc kits 3axis Nema 23 Stepper Geared Motor with 15:1 Gear Ratio252oz in/0.6A

I'm pretty sure I have it wired correctly. I have used a parport tester to send signals to the controllers and I can get the motors to make humming and squeally noises but the motors won't turn. Can someone help? :drowning:
