Check the pins.h file with pins definition for the motherboard defined in config.h and write down the numbers of Xstep and Xdir and Xenable. Download and open the source files for the electronics of your motherboard and check these lines on which uC pin they are. First ensure if the pins numbering are correct and specifically numbers are not mixed to each other. If that passes, try multimeter continuity to each from the specific uC pin to the place on driver, then resistance between the tracks, and then between each track and gnd and +5v or check anything else that looks particular. However i think the pins definition numbers are mixed coz i see the motor does make a move and i suppose it would require more than a short to make it behave like in vid, e.g. change dir on its own and behave like that. You could also check the sleep pin if the driver has any, because that also resets the ustep position to a full position and could appear similar, tho i think its probably not the case with sleep.
