CNC 3D Printer Kit with Mega 2560 Board RAMPS 1.4 Controller Driver for Arduino

Description: Product Description If you have any questions, please contact customer service first, do not open disputes easily, thank you! Features: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.For 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 memory card to add - is now available from the Kliment - Sdramps.LED indicate when the heater output.Optional 2 motors connected to Z Prusa Mendel.Mega 2560:Microcontroller: ATmega2560Operating Voltage : 5VInput Voltage (recommended): 7-12VInput Voltage (limits): 6-20VDigital I/O Pins: 54 (of which 14 provide PWM output)Analog Input Pins: 16DC Current per I/O Pin: 40 mADC Current for 3.3V Pin: 50 mAFlash Memory: 256 KB of which 4 KB used by bootloaderSRAM: 8 KBEEPROM: 4 KBLCD 12864:3D 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 memory card, and then print the file via the LCD control panel. This version is an upgraded version of reprap smart controller.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.Features: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.A4988 Driver:A4988 is a complete microstepping motor driver with built-in translator for easy operation.This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A.A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes.A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep.There are no phase sequence tables, high frequency control lines, or complex interfaces to program.A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed).In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime.Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption.Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption.Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.Features:Low RDS (On) OutputAutomatic current decay mode detection / selectionMix with slow current decay modesSynchronous rectification for low power dissipationInternal UVLOCross-current protection3.3 and 5 V compatible logic supplyThermal shutdown circuitryGround fault protectionLoad short-circuit protectionOptional step five modes: full, 1/2, 1/4, 1/8 and 1/16Package included:1 * RAMPS 1.4 Controller1 * AtMega 2560 CH340 Board1 * RAMPS LCD 12864 motherboard6 * Endstop Mechanical Limit Switch With Cables5 * A4988 Stepper Motor Driver5 * Heatsink1 * USB Cable1 * L type adapter plate2 * FC cable About Us We accept all payments authorized by eBay.
