研究 | 关于GEN_v1.0(ramps1.3)扩展板扩展9轴的方法

admin 本站

需求背景：

无论是GEN_V1.0 或 ramps1.3，步进电机默认最多支持5轴，即X、Y、Z、E0、E1。

而Marlin2.0固件最多支持6个挤出机（E0E1E2E3E4E5）,那如何在不更换主板的情况下让主板也支持6个挤出机呢？

实践过程：

实验对象是MKS_GEN_V1.0主板，先在Marlin-bugfix-2.0.xMarlinsrcpins文件夹内找到 pins_MKS_BASE.h 右键，打开方式，用写字板打开。

因为，ramps1.3扩展板电路设计是开源的，所有的pin口引脚都可以自行配置，如果想关闭当前功能，pin 值可设为 -1

右键打开写字板.jpg 用写字板打开

#if HOTENDS > 6 || E_STEPPERS > 6 //加热头设为6，E轴驱动器设为6

#error "MKS BASE 1.0 supports up to 2 hotends / E-steppers. Comment out this line to continue."

#endif

#define BOARD_NAME "MKS BASE 1.0"

// Heaters / Fans

//加热棒 / 风扇

// Power outputs EFBF or EFBE

#define MOSFET_D_PIN 7 //此为，第二加热棒的控制引脚

#define CASE_LIGHT_PIN 2

// M3/M4/M5 - Spindle/Laser Control

//此为，开启cnc雕刻机主轴的pin口

#define SPINDLE_LASER_PWM_PIN 2 // MUST BE HARDWARE PWM 必须连接MOS控制模块

#define SPINDLE_LASER_ENABLE_PIN 15 // Pin should have a pullup! 雕刻机主轴使能，必须串联一个上拉电阻

#define SPINDLE_DIR_PIN 19 //主轴方向切换控制引脚

#include "pins_RAMPS.h" //除以上几项，其它的控制引脚全部指向pins_RAMPS.h这个文件

下一步，打开也是用写字板，打开"pins_RAMPS.h" 文件。
