  • Ramps 1.4 Controller Board
  • This list is Pololu trillion rupiah , or ramps short. It was designed as a low-cost small package
  • RepRap needs to accommodate the entire electronics . Oblique interfaces with the powerful
  • MEGA platform Mega , and have plenty of room for expansion. On the stepper drives and a MEGA shield extruder control electronics for easy maintenance , replacement parts , upgrades and expansion capabilities , including plug-in modular design . In addition, some expansion boards can be added to the system , as long as the main ramp plate is saved to the top of the stack
  • The board is mainly based on Adrian ‘s Pololu_Electronics and work Tonok ‘s . The proposed anti- Vick copper etching method . Vick is also inspired by the work of EasyDrivers . Adrian’sPololu_Electronics circuit design mainly based on Joaz RepRapSource.com provide initial pin definitions and many design improvements. Too much inspiration , advice, and from Prusajr, Kliment, Maxbots, Rick, and many other ideas RepRap community.
  • It has Cartesian robots and regulations of the extruder .
  • Extended to control other accessories.
  • Heater / MOSFET outputs and three fan thermistor circuit.
  • Integration of additional security 5A and component protection
  • Control of additional heating bed 11A fuse
  • Suitable for 5 Pololu stepper driver board
  • Pololu board pin socket, so they can be easily replaced or removed for future designs .
  • I2C and SPI pins left for future expansion.
  • Hooked into all MOSFET PWM pin versatility.
  • Servo type connector is used to connect to the end stop , the motor and the light-emitting diodes.
  • These connectors are gold-plated , rated current of 3A, very compact.
  • On the SD card to add – is now available from the Kliment – Sdramps
  • LED indicate when the heater output
  • Option 2 motors connected to Z Prusa Mendel

  • 12864 LCD Controller Board
  • 3D printers use LCD control panel, are ramps extension accessories. LCD control panel through which you can achieve spooling is the 3D model Gcode files are copied to the SD card, and then print the file via the LCD control panel. This version is an upgraded version of reprap smart controller.
  • DRV8825 Stepper Motor Driver
  • The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough. The module has a pinout and interface with our A4988 stepper motor driver carrier is almost the same, so it can be used as a better performance of the pull-down menu board replacement in many applications. DRV8825 features an adjustable current limit, over current and over temperature protection, six micro-resolution (down 1/32-step). It uses 8.2 – 45 V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).
  • A simple steps and direction control interface
  • Six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step
  • CAN interface directly with 3.3 V and 5 V systems
  • Over-temperature thermal shutdown, over current shutdown, under voltage lockout
  • Short to ground short circuit load protection
  • 4 Layer 2 oz copper PCB, in order to improve heat dissipation
  • Exposed solder ground below the bottom of the driver IC on the printed circuit board pad
  • Module size, pin and interface matching A4988 stepper motor driver operators in many ways
  • Adjustable current control lets you set a potentiometer, which lets you use the stepper motor’s rated voltage or more, in order to achieve a higher rate of maximum output current step
  • Intelligent chopping control automatically selects the correct current decay mode (fast decay or slow decay)
  • Maximum 45 V supply voltage
  • Built-in voltage regulator (the need for any external logic supply voltage)
  •    Limit Switch End stop
  •    Quality switching elements.
  •    Customized high quality connection, using 22AWG wire, copper wire inside is very thick, can be
  •    resistant to current 2A, 300V voltage. An insulating layer over a wide range of temperatures, up to
  •    80 degrees. Is the common connection of thin copper wire can not match. Not easy to pull off, plug
  •    it convenient, for ease of use, plug the other side to do the one, you can use the direct plug.
  •    Red line connecting VCC (ramps of +)
  •    Connect the black wire GND (ramps of -)
  •    Green Line connection SIGNAL (ramps in s)
  •    tips: Under normal circumstances, the system must be configured to at least three mechanical switches.
  •    Pros: Easy to install, the more common styles.
  •    Disadvantages: easy to wear and tear of mechanical parts, service life is shorter
