int esp_set_dac_offset(long axis, float offset)

long axis
axis number from 1-6
float offset
DAC offset from +1.0 volt to -1.0 volt

esp_set_dac_offset() defines DAC offset compensation for the specified axis. DAC
offset takes affect immediately after the command is processed by the DSP.
Save DAC offset to non-volatile flash memory with the save_parameters() command.
This will cause the DSP to automatically use this value after system reset or reboot.
esp_get_dac_offset() reports the present DAC offset compensation used for the speci-
fied axis.
DAC offset compensation is necessary on servo axes to prevent motor drift during motor
off conditions.
