الميزات الأساسية

• LCD 12864 with Controller: The controller contains a SD-card reader, an rotary encoder and a 128*64 dot matrix LCD display, which enables it to achieve calibration, axes movements such actions. It is available to print the 3D designs without PC, jus
• 2560 Control Board: The microcontroller has 54 digital input/output pins(of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs(hardware serial ports), a 16MHz crystal oscillator, a USB connection, a power jack, an ICSP header and a rese
• RAMPS 1.4: As a driver expansion board, it has plenty room for expansion; more expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. Additionally, modular design includes plug in stepper drivers
• A4988 Driver Module: This module has 5 selectable step modes(full, 1/2, 1/4, 1/8 and 1/16), automatic current decay mode detection and selection(fast decay or slow decay), thermal shutdown circuitry, crossover-current/ground fault/load short-circuit
• DRV8825 Driver Module: It features 6 different step resolutions(full, 1/2, 1/4, 1/8, 1/16 and 1/32), adjustable current control for a higher step rate and maximum output current, over-temperature thermal shutdown, over-current shutdown, under-voltag
