I'm new to the RepRap community and I'm trying to build my own 3d printer. I have Nema34 stepper motors, DM860I drivers, 12V20A PSUs and a Rumba control board with a USB connection to my laptop. Everything seems to be wired correctly but when I connect to the control board the TX/RX led flashes intermittently and when I try to jog the motors on cura the led flashes every time I click "jog". The problem is that the motor doesn't move at all. I've tried replacing the usb cable and double checking my drivers, but no luck. Any other trouble shooting I can try?
