先安裝Arduino IDE
Arduino IDE Version 1.05
http://arduino.cc/en/Main/Software

首先用 Arduino IDE 開啟 Marlin 的 project


打開Arduino IDE, 選Com port

選Board

Open Project
open.JPG


選Marlin.pde 或Marlin.ino
Openfile.JPG



下載Marlin源碼你會見這些file

在Configuration.h內，要依控制板的型號設定對應 MOTHERBOARD 的參數
  1. // SERIAL_PORT selects which serial port should be used for communication with the host.
  2. // This allows the connection of wireless adapters (for instance) to non-default port pins.
  3. // Serial port 0 is still used by the Arduino bootloader regardless of this setting.
  4. #define SERIAL_PORT 0

  6. // This determines the communication speed of the printer
  7. #define BAUDRATE 250000
  8. //#define BAUDRATE 115200

  10. //// The following define selects which electronics board you have. Please choose the one that matches your setup
  11. // 10 = Gen7 custom (Alfons3 Version) "https://github.com/Alfons3/Generation_7_Electronics"
  12. // 11 = Gen7 v1.1, v1.2 = 11
  13. // 12 = Gen7 v1.3
  14. // 13 = Gen7 v1.4
  15. // 3  = MEGA/RAMPS up to 1.2 = 3
  16. // 33 = RAMPS 1.3 / 1.4 (Power outputs: Extruder, Bed, Fan)
  17. // 34 = RAMPS 1.3 / 1.4 (Power outputs: Extruder0, Extruder1, Bed)
  18. // 4  = Duemilanove w/ ATMega328P pin assignment
  19. // 5  = Gen6
  20. // 51 = Gen6 deluxe

因為用上了LCD & SD Card 模組所以亦要改下面呢段//LCD and SD support

溫度探頭的設定要改#define TEMP_SENSOR_0,#define TEMP_SENSOR_1,#define TEMP_SENSOR_2,TEMP_SENSOR_BED
  1. //===========================================================================
  2. //=============================Thermal Settings  ============================

  9. // -1 is thermocouple with AD595
  10. // 0 is not used
  11. // 1 is 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
  12. // 2 is 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)
  13. // 3 is mendel-parts thermistor (4.7k pullup)

除左LCD不能作中文顯示其實在language.h 內的"#define LANGUAGE_CHOICE 1"改其他相應的數字便可

這是最低溫度保護的設定,基本上是合香港使用不用改,就算在北方有雪的地方使用室內溫度也不會太低吧!主要是預防測溫線短路
  1. // The minimal temperature defines the temperature below which the heater will not be enabled It is used
  2. // to check that the wiring to the thermistor is not broken.
  3. // Otherwise this would lead to the heater being powered on all the time.
  4. #define HEATER_0_MINTEMP 5
  5. #define HEATER_1_MINTEMP 5
  6. #define HEATER_2_MINTEMP 5
  7. #define BED_MINTEMP 5
複製代碼
這是最高溫度保護的設定,基本上是不用改,主要是預防測溫線開路或測溫元件移了位而不停加熱產生危險
  1. // When temperature exceeds max temp, your heater will be switched off.
  2. // This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure!
  3. // You should use MINTEMP for thermistor short/failure protection.
  4. #define HEATER_0_MAXTEMP 275

  6. #define HEATER_2_MAXTEMP 275
  7. #define BED_MAXTEMP 150

#define EXTRUDE_MINTEMP 170是防止在170度以下時用家把擠出機驅動,如果在測試時你真的想在溫度不足情況下要轉動擠出機可把它改低一點
  1. //this prevents dangerous Extruder moves, i.e. if the temperature is under the limit
  2. //can be software-disabled for whatever purposes by
  3. #define PREVENT_DANGEROUS_EXTRUDE
  4. //if PREVENT_DANGEROUS_EXTRUDE is on, you can still disable (uncomment) very long bits of extrusion separately.

複製代碼
定義工作空間的參數 (單位為mm),如果你的heatbed不是205x205便要修改
  1. // Travel limits after homing
  2. #define X_MAX_POS 205

由於編碼器順時針轉動時LCD游標向上走不是我的習慣所以pins.h要改#define BTN_EN1 33 及
      #define BTN_EN2 31
  1.     #ifdef REPRAP_DISCOUNT_SMART_CONTROLLER
  2.       #define BEEPER 37
