at first when I used it it worked decently, but after a while it started to cause problems, not to see the sensors, when I attach the wheel to the device it doesn't see any sensor, neither the one from the hub, nor radial and axial, practically the stand cannot be used. I sent an email to ra-co service a few weeks ago and no one answered. I think it's something from the settings, but I don't know what to do with it. I can't attach pictures of the problem because I'm new here, please if you know how to help me, because I don't know what else to do. thanks a lot
