I liked the idea of the Hackaday tape measure trick, but I wasn’t willing to cut up any of my tape measures to do it. Instead I created a pretty simple solution using a spare bearing and a counter weight (not sure if that’s the right term). The counter weight is just a box that fits around the cable and is filled with a few nuts and bolts for the weight. I’ve been testing it all weekend and it keeps the cable off the table easily. I’m open to hear any suggestions or concerns.
I think the weakest spot is where the cords go into the stepper motor, so I may need to add some reinforcement there.
