I’ve managed to automate my vertical blinds with an external blind motor like many others. The problem is that with vertical blinds the draw string is usually a cord and the tilt is beaded. Since the cord is smooth, it inevitably slips and loses calibration. I have improved things by using an elastic band but it’s not perfect. A beaded chain would not have this issue.
Has anyone any experience changing the smooth cord with a beaded chain? Or seen any online resources showing how to do this?
