. Thanks for the help. one more question. How does an encoder lose track on rapids and not at lower speeds?
The encoder uses rotating glass scales, read by a laser similar to a CD/DVD drive. So it gets dirty or the laser fails or gets weak are two ways. Most encoders now are 8000 lines or signals per single revolution, very delicate. So, slowing them down will help them out but not fix the problem.
There are other things too like wires, but those are two main ones.
