Setting Defaults

Almost every $ Setting has a default in firmware. You can restore all your settings to the defaults by sending the $RST=$ command. Most setting defaults can be placed in your machine definition file using a line like this #define DEFAULT_X_STEPS_PER_MM 200.

Settings that configure multiple axes like $Stepper/DirInvert=XZ are stored internally as a binary bit mask in the format 00CBAZYX. This mean the bits for XZ are 00000101. This would be stored as the number 5.

#define DEFAULT_HOMING_DIR_MASK 5

Note: You can see all the values that you have changed from the defaults by sending the $Settings/ListChanged or $SC command.
