Any other ShapeOko2 owners notice some of their steppers have more grab when powered off than others in the shipment? Any idea how this will affect the movement of the machine?

Oh. Do you think the wires were touching and making a braking situation? I saw a youtube video where a guy was doing position control with normal DC motors and he would short all the wires to make it stop. I didn’t consider the idea that the same thing would happen with a stepper motor.
+Peter van der Walt Thanks much for the info. 
This isn’t CNC but is a good video showing how some of the caps n mosfets can effect their free play…
@NathanielStenzel I read, at some point in time, this is a great way to find your poles on a 4 wire stepper. Ordered some knock-off steppers and tried this as the wire colors were not accurate. Took a lot of spinning but I could find the proper a+/- and b+-. Resistance will drop when you cross the proper poles.
Hope the build is coming along great.
I ended up with the braking again and disassembled and reassembled the wiring a few times and then realized that if you hook two Y motors together, you make a complete circuit. DOH. How slow was that of me? lol
