![]() ![]() #define N_HOMING_LOCATE_CYCLE 2 // Integer (1-128) This help in preventing overshoot and should improve repeatability. Number of homing cycles performed after when the machine initially jogs to limit switches. #define HOMING_CYCLE_1 (1<<Y_AXIS) // COREXY COMPATIBLE: Then home Y #define HOMING_CYCLE_0 (1<<X_AXIS) // COREXY COMPATIBLE: First home X #define HOMING_CYCLE_0 ((1<<X_AXIS)|(1<<Y_AXIS)) // NOT COMPATIBLE WITH COREXY: Homes both X-Y in one cycle. ![]() NOTE: The following are two examples to setup homing for 2-axis machines. #define HOMING_CYCLE_2 // OPTIONAL: Uncomment and add axes mask to enable #define HOMING_CYCLE_1 ((1<<X_AXIS)|(1<<Y_AXIS)) // OPTIONAL: Then move X,Y at the same time. #define HOMING_CYCLE_0 (1<<Z_AXIS) // REQUIRED: First move Z to clear workspace. Z-axis first to clear, followed by X & Y. NOTE: Defaults are set for a traditional 3-axis CNC machine. This firmware was compiled with some changes to file config.h to perform homing only on XY and to set “zero” after homing cycle. This firmware comes from master branch of gnea/grbl aligned to the commit of 30 august 2019. File is the same you can download from here without any customization. This firmware comes directly from official grbl site. Here is a list of the firmware available for install via LaserGRBL flash tool. Usually you can find it embedded on the top of a motor driver board. Arduino UnoĪrduino Nano is the small one. Usually you can find it in a sort of “sandwich” with motor driver CNC shield. Here you should select your arduino board.Īrduino UNO is the big one. In these cases it is necessary to contact the supplier to get the customized firmware. S ome machines need a “custom” firmware to work, for example, because the manufacturer used pin connections other than the standard used by grbl. If you want to update the GRBL version installed on your engraver to have all the advantages of the latest v1.1 version, or if you need to re-program it after some error, of if you want to move a benbox engraver to grbl, LaserGRBL allows you to do this by installing from a list of selected firmware. ![]()
