상품명:  MKS mini 

주문단위: MKS MINI  1개

주문전 주의사항

1. 모터드라이버 DRV8825가 PCB에 직접 납땜이되어 있어 고장시 교체가 어려움.

    구매후, 보드 불량시에는 교환/반품이 안되니 신중하게 구매 바랍니다.

2. 보드에 사용되는 12V전원은 아답터형 잭이 부착되어 있음

    (SMPS사용시는 전선을 이용해서 납땜을 해서 사용해야됨)

3. 히팅베드 구동을 지원하지 않음.

    (단, MOSFET모듈을 별도로 달면 히팅베드 사용이 가능함) 

4. 듀얼노즐을 지원하지 않음. 싱글노즐에서만 사용가능함.

Overview

MKS MINI is a feature all-in-one electronics solution for Reprap and

other CNC devices.It features an onboard ATmega2560.

It's four motor outputs are powered by DRV8825 stepper drivers.

Feasures

The board can use the same firmware as Ramps1.4.

The mounting hole locations is the same as Arduino Mega2560.

The power supply with 7805, more stable and reliable than the 1117,

but only supports 12V.USB to serial modules is 16U2, the same as

Arduino Mega2560.Without hot bed heating output, but has bed

thermal interface and bed control signal interface.

Features

• Arduino MEGA compatible Atmega2560 processors are compatible with all RAMPS class firmware
• Easy DISPLAY + SD-CARD connector,RepRapDiscount
• SmartController compatible pin header on board
• Firmware can use the same configuration as ramps1.4
• 2x temperature ADC connectors for thermistors
• 모터 드라이버 DRV8825 4개(X,Y,Z,압출기)가 PCB에 직접 납땜이 되어있음.
• DRV8825고장시 납땜으로 교체해야됨으로 어려울수 있음 
• 2x PWM capable power mosfet outputs with voltage selector for MainPower.(Extruder0,Fans)
• 6x end stop connectors with power supply Xmin/Xmax/Ymin/Ymax/Zmin/Zmax
• 4 layers PCB, optimize heat dissipation.
• Recoverable fuse for short-circuit protection.

MKS MINI can easy use RepRapDiscount Smart Controller 

and RepRapDiscount Full Graphic Smart Controller

You only need connect Smart Controller's Exp1 to MKS MINI's Exp1,S

mart Controller's Exp2 to MKS Base's Exp2.

Firmware

This section will show you how to get firmware into your controller and run

it with basic settings.Software required: Arduino IDE, Choice of firmware

( Marlin or Repetier or Sprinter ), Pronterface

1.The VCP drivers will install a COM Port on your computer for the MKS MINI,

you can check what port number was assigned by going to your device manager

and click on Ports(COM & LPT) look for something that says "USB Serial Port(COM3)"

where COM3 is you assigned port number(will vary from PC to PC). Remember

this number as you will be using it later in configuring other software.

2. Install Arduino IDE - Download and extract the Arduino IDE .

3. Get your firmware - While you can use most firmwares out there, we will use

Marlin as an example. Download and extract Marlin or any other forks of the

firmware that you prefer/need.

4. Upload firmware - Run the Arduino IDE (arduino.exe).

Select your board - Click on Tools -->Board -->Arduino Mega 2560,

Select your serial port - Click on Tools-->Serial Port-->(select your COM

port for the X3 USB, you can check this in Device manager)

On Arduino click File-->Open -- then point to your Marlin Download and

select Marlin.pde. With Marlin loaded on the IDE window, click on the

tab that says "configuration.h". These are the basic entries that you

need to change to get the X3 working.

#define BAUDRATE 250000 //This will work fine for the MKS Gen

#define MOTHERBOARD 33 //33 is for RAMPS which the MKS GEN is compatible with MOTHERBOARD 34

#define TEMP_SENSOR_0 3 //If you have the NTC 100K 

#define TEMP_SENSOR_1 0

#define TEMP_SENSOR_2 0

#define TEMP_SENSOR_BED 0 //If you have the NTC 100K 

These entries are the only ones you need just to get the MKS Gen running.

Once you get it to upload you can now test most features of the board.

You will need to tweak the settings on the configuration file for your printer.

5. Upload(or compile to test) Marlin - While still on the Arduino window

Click on the Triangle inside the circle to do a test compile, this makes sure

that the firmware does not contain errors( you can skip this)

Click on the arrow pointing to the right inside a square frame to upload firmware

to the board. If everything goes well you'll see a "Done Uploading" message

near the bottom of the Arduino window.
