For future reference there are several ways to protect the encoder wires to prevent them from breaking (being broken).

1) I read in the Q&A that it's legal to use some silicon caulking as a strain relief on the encoder connector.

2) Loop the wire around the motor and zip tie it in place. (use the heat shrunk part of the cable as a strong anchor point.

3) Restrain any excess wire by zip tying it to the frame.

4) Make a cover to go over the motor controller to prevent anything catching on the encoder (or any other) wire.

Bottom line... any loose wire is an accident waiting to happen.
