Build Instructions for the 3D Printed G-Scale Train System

All of these parts should be 3D printed.

1. Take the base plate and install the motors as follows:

2. Flash the NodeMCU with the following firmware so that you can upload the Arduino code: How to Flash NodeMCU Firmware in ESP8266 : 7 Steps - Instructables
3. Upload the train_system.ino code to the NodeMCU: Train_Control_System/train_system/train_system.ino at main · CarviFPV/Train_Control_System
   a. You can do this as follows: How to Setup and Program NodeMCU ESP8266–Complete Guide
4. You should now be able to access the interface. The Wi-Fi SSID is: TrainAP and the password is: 12345678
5. You should now see this interface on http://192.168.4.1:

6. Wire the pins between the NodeMCU and the motor driver (L9110S H-bridge Stepper) as follows:
   • motor1A = D1
   • motor1B = D2
   • motor2A = D4
   • motor2B = D3
7. Here are a few more pictures of the wiring

8. The battery holder goes underneath the locomotive as follows:

9. The cockpit can be used to install an on/off switch.

10. Screw the remaining parts together.

11. It should now look like this:
