DetailsOverview1. For metal casing printers, it is prone to produce interference viaconnecting mainboard with cable. MKS BASE2 solvesthis problem by integrating the SD card directly on the main board.Then,it is perfect anti-interference and excellent stability.2. MKS BASE2 Uses 8825 instead of 4982, which can support 32and 16 microsteps.3.SD card slot on LCD 12864 or 2004 will be not available.4. In order to reduce the interference, MKS BASE2 increases largefilter capacitance on power section.5. Other functions are exactly the same with MKS - BASE.Please visit our github to download firmware:github.com/makerbase-mksFeatures :1.All functions integrate in one board that simplifies combinationof interfaces on Ramps1.4 and solves failure-prone problem.2. Use 8825 as motor drive, pack in SOP .3.4 layers PCB, optimize heat dissipation.4.Support 12V-24V power input.5.Can be directly connected Ramps1.4, 2004LCD control panel.and 12864LCD control panel.6.Firmware can use the same configuration as ramps1.4 .MKS Base2 prototype photo

1. USB VCP Drivers - MKS Base uses the newer FT232 USB to UART chipand it needs the updated VCP(virtual com port) drivers from themanufacturer's website . Download the correct version for your operatingsystem or you can get the executable version for Windows(easier).Windows Vista/7 may try to do an update to locate the proper driversbut it is recommended to install the FTDI drivers for better performance.The VCP drivers will install a COM Port on your computer for the MKS Base,you can check what port number was assigned by going to your devicemanager and click on Ports(COM & LPT) look for something thatsays "USB Serial Port(COM3)" where COM3 is you assigned portnumber(will vary from PC to PC). Remember this number as you willbe 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 orany 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 yourCOM port for the X3 USB, you can check this in Device manager)On Arduino click File-->Open -- then point to your Marlin Downloadand select Marlin.pde. With Marlin loaded on the IDE window, clickon the tab that says "configuration.h". These are the basic entriesthat 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 MKSGEN 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 3 //If you have the NTC 100K
- This section will show you how to get firmware into your controller and
- run it with basic settings.
- Software required: FTDI USB drivers, Arduino IDE, Choice of
- firmware ( Marlin or Repetier or Sprinter ), Pronterface.
- 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 s
- ure 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.
