![]() The 101 adds Bluetooth® Low Energy capabilities and has an on-board 6-axis accelerometer/gyroscope, providing exciting opportunities for building creative projects in the connected world. Can be configured in configuration.h or by M-code.The Arduino 101 is a learning and development board which contains the Intel® Curie™ Module, designed to integrate the core's low power-consumption and high performance with the Arduino's ease-of-use. The following formula will yield the 8-bit binary value, W v, to be entered into firmware or directly over SPI. This means the adjustable voltage range is 0 to 1.66 volts. Note the A4982 is set to be limited to 2A. You can verify the voltage for each driver by plugging the reference voltage (V REF) measured at the X_REF test point (Y_REF,etc for the other drivers) in the following formula: Ideally you should start with 70%-90% of maximum. I TripMAX is the current the stepper motors are rated for. R S, the value of the sense resistor on RAMBo is equal to 0.1Ω. The firmware sets the current at every boot and The following formula from the Allegro datasheet describes how to set the reference voltage: I TripMAX = V REF/(8 X R S). The current for the stepper motors is set by firmware controlling the 8-bit digital potentiometer. If firmware is compatible with RAMPS it can run on RAMBo with minimal modifications. One of the key features of RAMBo (like most other RepRap electronics) is the ease of entry for development and research. Repetier-Firmware has good support for RAMBo. You can adjust the motor driver settings in Configuration_adv.h: #define MICROSTEP_MODES and #define DIGIPOT_MOTOR_CURRENT You will likely need to tune the PID and DEFAULT_ settings to mach your hardware.įor some computers you may also need to set #define BAUDRATE 115200 to get communications. For a Epcos 100K thermistor on Extruder0 and HeatedBed: The TEMP_SENSOR needs to be set to match your configuration. You will need to use show package contents on the Arduino.app to access it's contents and add the files.įor Marlin you will at least need to set the following variables in configuration.h: Firmware may not work as expected if the firmware developer expected the add on folder to be installed.Ĭopy Rambo folder from Marlin/Arduinoddons/Arduino_1.x.x/hardware/ into /Applications/Arduino.app/Contents/Resources/Java/hardware. You will not have functionality on the extended ports. ![]() Without the add ons you can use Arduino Mega2560 from Arduino>Tools>Board>. ![]() Once the add ons are installed you can select RAMBo from Arduino>Tools>Board> ![]() The add ons can be found in or it may be included with your firmware(i.e. You should end with a boards.txt file at arduino-1.0.5/hardware/rambo/boards.txt. The add ons need to be copied into your Arduino application's hardware folder. RAMBo can operate with the Arduino app as an Arduino Mega2560, but it is best to install the RAMBo Arduino addons. These pins are used for LCD interface or external stepper drivers. Marlin and Repetier-Firmware (and others?) have extended support for RAMBo that takes advantage of the Atmega2560 MCU's pins that are not available on Arduino Mega2560. These instructions are for legacy versions of Arduino! (1.0.x) At the bottom of the list will be the option to install the RepRap Arduino Mega BOard (RAMBo). Open the Board Manager and the list boards will automatically update. The Board Manager is found at the top of the Tools->Board selection menu. Add the following URL to "Additional Board Manager URLs" section. Instead of manually installing the Rambo addon's you can now install them from the Arduino Board Manager.įrom the Arduino File menu select Preferences. (# = Port as shown in device manager)Įnsure the port is not in already in use.Ĭheck that the yellow led blinks twice on a manual reset. In Configuration.h, change motherboard setting depending on board (Rambo or Mini-Rambo):Ĭustomize the rest of Configuration.h for your printer as needed: ENDSTOP_INVERTING, STEPS_PER_UNIT, lcd support, sd support, etc. Install the Rambo board addon (instructions below). The RAMBo (RepRap Arduino-compatible Mother Board) hardware is compatible with most of the RepRap firmwares.įor beginners that want to modify their printer, firmware can be uploaded with the Arduino IDE.
