I didn't read all of this, but just installed my 4th and found a lot of goofy things between the machine and the manual and the kit.

Mine came with the wrong wires, it had 770 wires, not 1100 wires. (labels) So I got out the meter, and found that it was DC power not AC like the driver shows. So I wired it up correctly even though the wire labels are wrong. I plugged it in and unplugged it while the machine was on (like Don) and haven't had any issues.

Doesn't really matter if is it is DC current, when the plug is unplugged hot while current is flowing though the stepper inductive coils a L di/dt voltage is generated. I have personally measured several hundred volts generated when 24V DC relay was energized or de-energized due to L di/dt.
