I find this model from Milicjovan and I like how simple it is with just basic stuff. I then run into the problem that the original model have some tolerance issues, is missing the code and I saw a few having the same problem so I remix it fixing all the issues I find and added the code for an arduino board with a 28BYJ-48 stepper motor and a Driver (ULN2003).

It works really good and with the code I been able to get it to spin with around 500g on top. If anyone know about electronic ( I am new to this part of 3D printing) I would like to know how can I upgraded with a better motor to have more speed, as the plate takes around 2 min to do a full spin and I need it to take videos of my prints.

Really good for 3D scanning tho and still work for my purpouse just not really efficiently.

hardware :

-Arduino

-28byj-48 stepper motor with driver

-4x 608 bearing (8x22x7mm)

-2 screws to mount the motor

PD: YES, I used 3D printed bearing and It works pretty good and YES, I put grease (automotive one, only I had at the time) everywhere making a mess hahaha but It did help reducing the friction and noise.

CODE:

// Include the Stepper library.

// This library comes with the Arduino IDE and simplifies controlling stepper motors.

#include <Stepper.h>

// Define the number of steps per revolution for your motor.

// Common values are 200 (for 1.8 degree/step motors) or 48 (for 7.5 degree/step motors).

// Check your stepper motor's datasheet for this value.

const int stepsPerRevolution = 200; // Change this to match your motor's specifications

// Create an instance of the Stepper library, specifying the number of steps

// and the pins connected to the motor driver.

// The order of pins might vary depending on your driver (e.g., ULN2003, A4988).

// For a 4-wire unipolar stepper motor directly connected to Arduino via a driver like ULN2003:

// Pin 1 (IN1) -> Arduino Pin 8

// Pin 2 (IN2) -> Arduino Pin 9

// Pin 3 (IN3) -> Arduino Pin 10

// Pin 4 (IN4) -> Arduino Pin 11

Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

void setup() {

// Initialize serial communication for debugging purposes.

// This allows you to see messages in the Serial Monitor.

Serial.begin(9600);

Serial.println("Stepper Motor Control Started");

// Set the speed at which the motor will turn.

// This is in RPM (Revolutions Per Minute). Adjust as needed.

myStepper.setSpeed(30); // Set motor speed to 60 RPM

}

void loop() {

// Step the motor one full revolution in one direction.

Serial.println("Moving clockwise...");

myStepper.step(stepsPerRevolution); // Move motor by 'stepsPerRevolution' steps

}

I am also gonna add a word file with the code just in case but is should be the same.
