With the bigger motor I can run the wall at 15 feet per. minute (fpm) with no problem, without a climber on the wall. I might be able to go faster but I haven’t tried it yet. I guess having tripled the available torque was a safe bet.
15 fpm is a quick but not a super fast climbing pace. For the endurance and interval workouts I have tried so far it is certainly fast enough. I will play with it and post an update when I find out what its top speed is.
I made up a simple plywood bracket and hung all the power supply and driver, off the gear box. This kept all the wiring nice and tight. You just have one power cable and one control cable running up to the bundle of stuff up top. It would also make things easy to enclose if you wanted to make a weather resistant version. For now the controller is sitting on a paint can next to the wall but I will be building a bracket to put it up around face level.
And here is a video of me climbing the wall at 14 fpm. It starts slow and ramps up to full speed by about 20 seconds into the video.
