@ -106,6 +106,27 @@ VAL=<value>`: Writes raw "value" into a register "register". Both
"value" and "register" can be a decimal or a hexadecimal integer. Use
with care, and refer to ADXL345 data sheet for the reference.
### [angle]
The following commands are available when an
[angle config section](Config_Reference.md#angle) is enabled.
#### ANGLE_CALIBRATE
`ANGLE_CALIBRATE CHIP=<chip_name>`: Perform angle calibration on the
given sensor (there must be an `[angle chip_name]` config section that
has specified a `stepper` parameter). IMPORTANT - this tool will
command the stepper motor to move without checking the normal
kinematic boundary limits. Ideally the motor should be disconnected
from any printer carriage before performing calibration. If the
stepper can not be disconnected from the printer, make sure the
carriage is near the center of its rail before starting calibration.
(The stepper motor may move forwards or backwards two full rotations
during this test.) After completing this test use the `SAVE_CONFIG`
command to save the calibration data to the config file. In order to
use this tool the Python "numpy" package must be installed (see the
[measuring resonance document](Measuring_Resonances.md#software-installation)
for more information).
### [bed_mesh]
The following commands are available when the
