In some cases, the robot may not be able to save deck calibrations. This is due to a poor connection on the USB mount which stores robot calibration data. Error message shown below:

Materials needed:

  • 2.5 Hex driver provided within the accessories of your robot


1. Using your 2.5mm hex driver remove the 4 screws which fasten the top acrylic panel and remove the panel by sliding and lifting.
