A section cut from cat-5 cable works well as does just twisting some normal insulated wire together. - Ensure that the step/dir signal cables are not draped over the odrive board, are not running in parallel to the motor or power supply cables. - If the above does not resolve your issue on V3.4 boards and lower try adding a ~22 Ohm resistor in series with the step and direction pins along with a ~ 4.7 nF capacitor between the ground pin and the step and dir pins such as shown [here](https://cdn.discordapp.com/attachments/369667319280173069/420811057431445504/IMG_20180306_211224.jpg). + +### Index search never completes + +There are some GPIO pin interrupt collisions on ODrive 3.6 that could cause index search to fail in certain conditions. If you are using both step/dir and index pins, we recommend disabling `step_dir_always_on`.
