Making Z module

To fix the z position of the Extruder module, I made the z axis module.

Electronic Board and Programing

Two stepper motor is used for z axis module. Those two stepper motor have to rotate samely to keep the same z position. And Z axis module is controled manualy using tact switch based on the my design concept.


stepper control board


stepper signal distribution board


controller(tact switch)


By using controller z height can be controled like a game.
The boards were in the following box. But controller was outside the box. Considering the structural strength, it should be into the box, but I wanted to move z axix module as a game based on my part of design concept "people are involved".

I wrote program with Arduino IDE. Program is follows. 
#include <avr/io.h>


#define A2 0//(1 << PA0) // H-bridge output pins
#define A1 1//(1 << PA1) // "
#define B2 3//(1 << PA3) // "
#define B1 4//(1 << PA4) // "
#define SwU 8//(1 << PA4) // "
#define SwD 9//(1 << PA4) // "

#define BASESTEPANGLE 1.8// 1ステップの角度
#define PulseWidth       (20.0)  // 1パルスの長さ msec



bool rotLock = false;
void setup()
{
    
    pinMode(A2, OUTPUT);
    pinMode(A1, OUTPUT);
    pinMode(B2, OUTPUT);
    pinMode(B1, OUTPUT);

    pinMode(SwU, INPUT);
    pinMode(SwD, INPUT);

    CLKPR = (1 << CLKPCE);
    CLKPR = (0 << CLKPS3) | (0 << CLKPS2) | (0 << CLKPS1) | (0 << CLKPS0);
    
    
    
}

void loop()
{
    
//clockwise();
//counter_clockwiese();
    
    if(digitalRead(SwU)==LOW){
      clockwise();
      
    }else if(digitalRead(SwD)==LOW){
      counter_clockwiese();
    }


}

void clockwise(){
    digitalWrite(B1, HIGH);//2in1
    digitalWrite(B2,LOW);//2in2
    delay(PulseWidth);
    digitalWrite(A1, HIGH);//1in1
    digitalWrite(A2,LOW);//1in2
    delay(PulseWidth);
    digitalWrite(B1, LOW);//2in1
    digitalWrite(B2, HIGH);//2in2
    delay(PulseWidth);
    digitalWrite(A1, LOW);//1in1
    digitalWrite(A2,HIGH);//1in2
    delay(PulseWidth); 
}
void counter_clockwiese(){
    digitalWrite(A1, LOW);//1in1
    digitalWrite(A2,HIGH);//1in2
    delay(PulseWidth);
    digitalWrite(B1, LOW);//2in1
    digitalWrite(B2,HIGH);//2in2
    delay(PulseWidth);
    digitalWrite(A1, HIGH);//1in1
    digitalWrite(A2,LOW);//1in2
    delay(PulseWidth);
    digitalWrite(B1, HIGH);//2in1
    digitalWrite(B2, LOW);//2in2
    delay(PulseWidth);  
}
