It is installed on Arduino Mega 2560-compatible boards and expands them with all the outputs required for printing without occupying the digital pins themselves.\u003c\/p\u003e \u003cp\u003eThe board individually controls four stepper motors for the axes and the filament extruder. The integrated 20*4 LCD display with control knob shows print progress, temperatures, and menus directly on the printer. This eliminates the need for a continuous computer connection during printing.\u003c\/p\u003e \u003cp\u003eThe heated bed and hotend can be operated with different current levels. The board detects the current temperatures of both elements via thermistor inputs and regulates them independently. This makes printer control possible without additional external electronics.\u003c\/p\u003e \u003cp\u003eApplications range from building a classic Cartesian printer and delta printers to Bowden extruders with direct motor control. Compatibility with numerous firmware variants allows flexible adjustments for different mechanical designs.\u003c\/p\u003e \u003cp\u003eAn Arduino Mega 2560 or compatible equivalent is required. The board needs a separate power supply for the motors and heaters, typically 12 V or 24 V from a suitable power supply unit. Software such as Marlin or Repetier is required and must be loaded onto the Arduino beforehand.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThis board is intended exclusively for building prototypes and for testing and development purposes, not for continuous operation in production facilities. The power supply must come from a suitable power source without a connection to the domestic electrical installation. If you are unsure about the wiring or before commissioning, consult a qualified electrician.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x Reprap Ramps V1.4 - Controller with 20x04 LCD, for 4* A4988\u003c\/li\u003e \u003cli\u003e1x Smart Adapter\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045112811869,"sku":"F23106174","price":11.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/reprap-ramps-v14-controller-mit-20x04-lcd-fuer-4-a4988-funduino-9213473.png?v=1791488823","url":"https:\/\/funduino.com\/en\/products\/reprap-ramps-v1-4-controller-with-20x04-lcd-for-4-a4988","provider":"Funduino","version":"1.0","type":"link"}
