It is well known that dc steppers generate voltage when they are moved when not under power. Numerous drives on numerous brands have blown when axes are moved by hand. Imagine the current generated if the machine was executing a rapid move of a few hundred inches per minute and the estop was activated, which of course removes power to the drives. Once the back EMF gets into the drive, it lets the magic smoke out. Blown drive.
2 fixes: 1) Forget about the estop and use the spacebar. Too many users think that the Estop is the "everyday stop", its not, never has been. 2) Search for and find the Leadshine tech document that specs a couple $40 aluminum caps, or an even more expensive shunt to absorb the generated voltage, and install one setup.
