I have a Nema 17 connected to the a4988 driver. When I have everything ready for operation, the engine makes an excessive noise and rotates uncontrollably and erratic. Try to change my Arduino board, bridge all my gnd, check the continuity of my cables, try another programming, change the driver, and none of that was the problem. Opinions??

I would need to see your connection diagram and your sketch.

Post an annotated schematic showing exactly how you have wired it, be sure to include all connections, power, ground, and power sources. Also following the forum guidelines post your code using the code tags.
