This year we used two AndyMark Absolute Encoders AM-2389 on our robot. Overall they worked exceptionally well, with one large exception. They are fully rounded. They don’t have a key or a flat, and they slipped frequently as a result. We tried 3D printed mounts, gaskets, adhesives, and even press fitting up until it we felt it was going to break, and it still slipped.
Do you use these encoders? Are we doing this wrong? How do you mount these? Thanks
