3D Printer RAMPS All in One plus “Complete 3D printer electronics in one Board”

Description

Features

Based Arduino 2560, RAMPS 1.4 pin compatible pin configuration, All in one solution for ultra-small, especially for MINI-type machines and new users in 3d printer build.

Provide a heating end, 240W MAX (where the range depends on the MOS parameters)

Support hot bed 240W MAX (maximum current does not exceed 10A, the proposed temperature control in 100 ℃ below)

Power supply: 12 or 24V DC (can use laptop power supply or other switching power supply)

Two thermometers (thermistor) inputs, one for the thermal head and one for the hot bed

Six-way limit switch, 3 min, 3 max (non-cost considerations recommended the use of six switches to avoid collision)

Reserved I2C expansion port, ESP-01 WIFI module interface, user-friendly to add functionality

All the way adjustable fan interface, two power connector (can be used for fixed output fan or LED and other equipment)

On-board 4-way two-phase stepper motor drive (based on Allegro A4988, maximum current limit 1.0A)

TF on-board deck, and perpendicular to the board, beautiful and convenient place

Integrated 2.4 inch 12864 display, can be realized in Chinese or English display (depending on the firmware may be)

Here you can Downlaod the FirmWare

Recommended with:

12-24V DC switching power supply (without hot bed 90W +, with hot bed 200W +) X 1

NTC 100K (default B value of 3950, or other specifications) Thermistor (line length according to the machine) X 2 (with two hot beds, without a hot bed like)

Drying tube 12-24V / 40W 

Hot bed / not more than 100 ± 10W X 1 

12-24V fan X 1 [(can also connect two parallel), for surface cooling when printing, but also increase the fan as the motherboard or the motor cooling] 

A number of wires 

SD card X 1

42 stepper motor (1.0A max) X 4 (or 5, Z-axis motor in parallel)

Wiring diagram:

Description:

1. The output voltage of the thermal head, hot bed and FAN / LED, PWM fan is equal to the input voltage. When using 12V power supply

 These interfaces are 12V, 24V power supply when using these interfaces are 24V

2. Limit switch is connected to S (signal terminal) / GND for mechanical limit switch (also connect to S (signal terminal) / GND / 5V, for photoelectric switch, at this time need to remove the white seat Son to welding pin)

3.I2C interface, from left to right as follows: SCL, SDA, GND, 5V
