Now you can test a connection.
- For "non bed-slingers" (e.g. one accelerometer), in Octoprint, enter `ACCELEROMETER_QUERY`
- For "bed-slingers" (e.g. more than one accelerometer), enter `ACCELEROMETER_QUERY CHIP=adxl345_x` where `adxl345_x` is the name of the chip as-entered (see: [bed-slinger](#bed-slinger-printers)).
