Warning: 1)Reversing +/- or otherwise incorrectly connecting power can destroy your electronics and cause fire hazard. 2)Do not plug or unplug and wire or module when power is on 3) Do not even touch the board when power is on or your hand has static charge (you can move static charge by touching metal tap). 4) The endstop pins are Signal - GND - VCC, instead of the VCC - Sig - GND like the rest of RepRaps boards. Make sure to wire them correctly. This is done to allow squeezing fatter traces on the printable board. 5) Test all electronics thoroughly before placing into service 6) Do not leave power supplied to electronics unattended, or run machines unattended due to the risk of fire and malfunction. 7) Once you start putting electricity into your RepRap - even at just 12 volts - you have to take basic, common sense precautions to avoid fires. Just in case these fail, test your workshop smoke detector. 4.  Marlin Firmware installation guide on MKS BASE Board Step 1) Download Arduino IDE from https://www.arduino.cc/en/Main/OldSoftwareReleases#previous. and install Arduino IDE (If you have already installed U8glib, please skip this step): Step 2) use USB cable to connect Arduino Mega2560 and your PC. Your pc should detect Arduino Mega2560 and install driver automatically. If driver can not be installed automatically, please download the driver: FAT 232 driver.rar. and unzip this file and run the installation program.(We have test this driver on Window XP and Windows 7. If the driver we provide doesn't work with your computer, please google the "FT232" ) Step 3)Install U8glib library into Arduino IDE. (If you have already installed U8glib, please skip this step) First: Download U8glib library from OSOYOO U8glib library. Then, in Arduino IDE ->Sketch->Include Library->Add Zip Library , select the zip file you just downloaded and load into IDE. see following picture: addzip Step 4) a) In Arduino IDE->Tools->Board select Arduino Mega 2560, b) In Tools->Port ->select the COM port which associated with Arduino Mega2560(see picture below) ide-2560 ide-comport Step 5)Download Marlin firmware: 2.8" TFT touch screen Marlin firmware(1.3 or 1.4),If you are using version 1.5, You must use the most recent version of Marlin ( http://marlinfw.org/meta/download/) and the newer version of Arduino compiler (Arduino 1.6.13) Unzip above file, you will see a folder called "Marlin". Step 6)In Arduino IDE->File->Open, find Marlin Folder and open Marlin Arduino File(Marlin.ino) Your IDE will compile the firmware and load it into board. There might be some warning error message during compiling, just neglect those message. In Marline folder, there is Configuration.h file which defines some important hardware config setting values. Please read following instruction to change the Configuration.h and configuration_adv.h file according to your hardware situation: Please be noted MKS board Z axis servo controller installation as following: If you have only one extruder and two Z axis servos, another servo should be connected to E1_MOT. If You have two extruders and two Z axis servos, Two servo on Z axis should be series connected to Z axis A)If you connect MKS Base board with two Z axis servo motors, please make following changes, In configuration.h line 248 to 253: #define INVERT_X_DIR false // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR true // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR false // for Mendel set to false, for Orca set to true #define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false in configuration_adv.h uncomment line 148 #define Z_DUAL_STEPPER_DRIVERS as following: #define Z_DUAL_STEPPER_DRIVERS // disable this line if you have only one Z motor B)If you connect MKS Base board with only One Z axis servo motors, please make following changes, In configuration.h line 248 to 253: #define INVERT_X_DIR false // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR true // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR false // for Mendel set to false, for Orca set to true #define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false in configuration_adv.h disable line 148 #define Z_DUAL_STEPPER_DRIVERS as following: //#define Z_DUAL_STEPPER_DRIVERS // disable this line if you have only one Z motor 5. MKS TFT 2.8 Touch Screen configuration (if you have already configured the MKS-TFT28, please skip these steps): Step 1) Pls download MKS-TFT_V2.0.0English.zip file from following link: http://osoyoo.com/driver/MKS-TFT_V2.0.0English.zip Step 2) Unzip the files and copy mks_pic, mks_config and mkstft28.bin files into a USB storage or SD Card. eghh Step 3) Connect with MKS board and Turn on power, the screen will show updating messages as per following pictures, as following pictures: IMG_20160725_145737 IMG_20160725_145749 Step 4) You may need to change baud rate to match MKS board. Normally the rate should be set to 115200. If this does not work, try other rates. IMG_20160725_145855 Step 5) Printing: Put your 3d module data file into the USB storage or SD card and put it into MKS-TFT28 , your 3D printer will start printing shortly.
