It is always great to see the more subtle problems and issues being identified and then solved, quite often, as in this case of the step motor, by a relatively simple and low cost fix (a couple of capacitors and diodes). A nice bit of fettling there.

It was also interesting to see the stationary cart 'bucking' backwards a little bit when the arm is being raised quickly, due to the momentum of the arm. There are some methods for reducing this bucking using the arm configuration and velocity control approaches. Another subtle issue needing some fettling.

Good job.

Much smoother motion.
