Reprap Ramps 1.4 kit + Mega 2560 + Heatbed mk2b + 12864 LCD Controller A4988

MK2B Heatbed

  • MK2B is the latest and the best type of heatbed money can buy as of today. 100% compatible
  • with all Prusa and Mendel 3d printer variants.
  • Color: Red
  • Size: 214mm x 214mm
  • Etching: 35um copper
  • Laminate: FR4 1.6mm
Ramps 1.4 Controller Board
  • 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
Mega 2560
  • Microcontroller : ATmega2560
  • Operating Voltage : 5V
  • Input Voltage (recommended) : 7-12V
  • Input Voltage (limits) : 6-20V
  • Digital I/O Pins : 54 (of which 14 provide PWM output)
  • Analog Input Pins : 16
  • DC Current per I/O Pin : 40 mA
  • DC Current for 3.3V Pin : 50 mA
  • Flash Memory : 256 KB of which 4 KB used by bootloader
  • SRAM : 8 KB
  • EEPROM : 4 KB
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.
DRV4988 Stepper Motor Driver
  • DRV4988 features an adjustable current limit, overcurrent and
  • overtemperature 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, overcurrent shutdown, undervoltage 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 Endstop
  • 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
