I would suggest manual operation. Attach timing pulleys to your threaded rods, wrap a timing belt around all four, and then just pull on the belt in either direction to raise/lower the table. The biggest trick here is that you have to splice the belt together on your own and you'd need to calculate the available throw vs screw pitch vs gear teeth to make sure your splice doesn't need to roll over the gears to get the height you need.
I probably talked to the same team you did at Houston. I’ve never made it, but think I grasp the concept. Using a belt like this , one side is mounted to the back of the last stage of the slide, then loops around to the front of the next stage, then to the back of that stage, and so on (just like in a string lift). After the last stage, the belt loops around the pulley attached to the motor, and then Is once again looped around the slide except in the opposite direction. (If you’ve ever strung a lift with two strings, it’s the same concept). You don’t need a pulley on any of the points the belt loop back, just something to minimize the friction of it rubbing. Also you’d need to find pulley for the output that can interface with the FTC motor output shafts, since most of the ones I find on amazon are for stepper motor shafts. Servocity might have something.
I just ordered this kit, I'll let you know how it goes.

Edit: Parts came in and everything is fantastic. Installed the dampers and it is amazingly quiet.
