So when my cnc job finishes there is a delay (not sure what it is maybe 10-30 minutes) until the stepper motors shuts off. When that happens, the Z-Axis usually drops (slowly) due to gravity of course.
Is there a way to adjust that delay via a gcode command or is that something in firmware that needs to be flashed.
I just want to extend the amount of time after the CNC is doing “nothing” before the steppers shut off.
Also, if you ever want to adjust the values in firmware, see this section in configuration_adv.h:
/**
* Idle Stepper Shutdown
* Set DISABLE_INACTIVE_? 'true' to shut down axis steppers after an idle period.
* The Deactive Time can be overridden with M18 and M84. Set to 0 for No Timeout.
*/
#define DEFAULT_STEPPER_DEACTIVE_TIME 1200
#define DISABLE_INACTIVE_X true
#define DISABLE_INACTIVE_Y true
#define DISABLE_INACTIVE_Z false
#define DISABLE_INACTIVE_E true
