Stepper motor issue

everything was working great last night. Come out this afternoon to work and the y2 motor not responding. looked at the wires and found the white was loose. tightened all back up and still nothing. swapped y1 and y2 and it responds but the y1 wont. any suggestions?

Might have arced and burned the chip. Xcontroller? Might want to open it and check for signs of damage.

Call Inventables support if it’s an Xcontroller.
