+ | 2.Configure Firmware parameter. | ||
+ | |||
+ | The following parameter need configured, others default. | ||
+ | |||
+ | #define BAUDRATE 250000 | ||
+ | |||
+ | It configures for SERBAUD. Note: the successful communication can be realized when the upper computer Baud rate is identical with Firmware Baud. The Baud can’t be modified freely. The common Baud : 2400,9600,19200,38400,57600,115200,250000. The last three are frequently used by 3D Printer. | ||
+ | |||
+ | #define MOTHERBOARD 80 | ||
+ | The parameter is used to configure board type. 3D Printer has many types of main board, but the IOs of all boards are different, therefore, the parameter has to correspond to the type of your board, or it can’t operate normally. The configuration of Rumba should be 80(single nozzle configuration). If it is other board, you can choose a suitable parameter with the annotation beside the board. | ||
+ | |||
+ | #define TEMP_SENSOR_0 3 | ||
+ | #define TEMP_SENSOR_BED 3 | ||
+ | |||
+ | The two parameters configure the type of temperature sensor respectively. They are the critical parameter to check if the sensor read temperature normally. It is can’t operate even has potential risk (burn the device and others) when the temperature readout is normal. You must modify depends on circumstance if you used other temperature sensors. | ||
+ | |||
+ | #define EXTRUDE_MINTEMP 170 | ||
+ | |||
+ | The parameter is to avoid the potential risks when the extrusion operates before reaching the appropriate temperatures. If it is used for other 3D Printer, such as printer of Chocolates, 45℃ is appropriate, so that the parameter configured to a lower value(such as 40℃). | ||
+ | |||
+ | const bool X_ENDSTOPS_INVERTING = true; | ||
+ | const bool Y_ENDSTOPS_INVERTING = true; | ||
+ | const bool Z_ENDSTOPS_INVERTING = true. | ||
+ | |||
+ | The three parameters configure the end stops types of three axes. The configuration is true, the end stop outputs 1 in default condition and outputs 0 in trigger condition. That is, mechanical end stop connects the AOF. If it connects the AON, true should be changed to false. | ||
+ | |||
+ | #define INVERT_X_DIR false | ||
+ | #define INVERT_Y_DIR true | ||
+ | |||
+ | It is easily to make mistakes in the above two parameters. The parameters are different in different machinery. However, in principle, the origin should be at lower-left corner of the print platform (origin: 0, 0), or at up-right corner (origin: max, max).then, the model printed is correct, otherwise, the printed is the mirror image of one axis, with the result that the wrong model direction. | ||

+ | #define X_HOME_DIR -1 | ||
+ | #define Y_HOME_DIR -1 | ||
+ | #define Z_HOME_DIR -1 | ||
+ | |||
+ | If the origin is the minimum, the parameter is -1; if it is the maximum, the configuration is 1. | ||

+ | These parameters are crucial to the printing size configuration. Fill in parameters by reference to the coordinate graphs. It is important to note that the origin is not the printing center and the real printing center usually at [(x.max - x.min)/2, (y.max -y.min/2)]. The coordinate of central position will be used in the slice tool. The printing center’s coordinate must correspond to the parameter configuration, or it will print to the outside of the platform. | ||

Quick Started Guide to program
Rumba board to 3D printer is just like the brain to human. Rumba fulfill the complicated printing through dominating all 3D Printer Accessories。It cannot operate directly without uploading firmware.
1.Download firmware-Marlin. Marlin firmware is born with powerful features and easy to use, therefore we just introduce Marlin firmware.
2.Configure Firmware parameter.
The following parameter need configured, others default.
#define BAUDRATE 250000
It configures for SERBAUD. Note: the successful communication can be realized when the upper computer Baud rate is identical with Firmware Baud. The Baud can’t be modified freely. The common Baud : 2400,9600,19200,38400,57600,115200,250000. The last three are frequently used by 3D Printer.
#define MOTHERBOARD 80
The parameter is used to configure board type. 3D Printer has many types of main board, but the IOs of all boards are different, therefore, the parameter has to correspond to the type of your board, or it can’t operate normally. The configuration of Rumba should be 80(single nozzle configuration). If it is other board, you can choose a suitable parameter with the annotation beside the board.
#define TEMP_SENSOR_0 3 #define TEMP_SENSOR_BED 3
The two parameters configure the type of temperature sensor respectively. They are the critical parameter to check if the sensor read temperature normally. It is can’t operate even has potential risk (burn the device and others) when the temperature readout is normal. You must modify depends on circumstance if you used other temperature sensors.

The parameter is to avoid the potential risks when the extrusion operates before reaching the appropriate temperatures. If it is used for other 3D Printer, such as printer of Chocolates, 45℃ is appropriate, so that the parameter configured to a lower value(such as 40℃).
const bool X_ENDSTOPS_INVERTING = true; const bool Y_ENDSTOPS_INVERTING = true; const bool Z_ENDSTOPS_INVERTING = true.
The three parameters configure the end stops types of three axes. The configuration is true, the end stop outputs 1 in default condition and outputs 0 in trigger condition. That is, mechanical end stop connects the AOF. If it connects the AON, true should be changed to false.
#define INVERT_X_DIR false #define INVERT_Y_DIR true
It is easily to make mistakes in the above two parameters. The parameters are different in different machinery. However, in principle, the origin should be at lower-left corner of the print platform (origin: 0, 0), or at up-right corner (origin: max, max).then, the model printed is correct, otherwise, the printed is the mirror image of one axis, with the result that the wrong model direction.
#define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR -1
If the origin is the minimum, the parameter is -1; if it is the maximum, the configuration is 1.
#define X_MAX_POS 205 #define X_MIN_POS 0 #define Y_MAX_POS 205 #define Y_MIN_POS 0 #define Z_MAX_POS 200 #define Z_MIN_POS 0
These parameters are crucial to the printing size configuration. Fill in parameters by reference to the coordinate graphs.

The coordinate of central position will be used in the slice tool. The printing center’s coordinate must correspond to the parameter configuration, or it will print to the outside of the platform.
#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0}
The rate of configuration back to origin, unit: mm/min. This parameter could be set default when you use the x-axis, y-axis synchronous belt drive and z-axis screw drive.
#define DEFAULT_AXIS_STEPS_PER_UNIT {85.3333, 85.3333, 2560, 158.8308}
These parameters are crucial to check if the printing size is correct. Parameters means that the pulse number needed at every axis when operating 1mm. they are correspond to x, y, z and e respectively. In most cases these number should be computed by yourself, but you can refer to: http://calculator.josefprusa.cz/#steppers So far we have configured the common parameters and could operate it. In addition, if the 2004LED need verifying, you should delete the “//” from “//#define REPRAP_DISCOUNT_SMART_CONTROLLER” to ensure the normal working.
