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
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。
