3D Printer Software Setup and G-code Introduction

Overview

• Purpose: Download and set up software for 3D printing.
• Aim: Simplify the process for beginners and provide step-by-step guidance.

Key Concepts

G-code

• Language for 3D printers.
• Consists of X, Y, and Z coordinates, and instructions on filament extrusion.
• Files from the internet are not usually in G-code format; they must be processed first.

Slicer Software

• Converts model files into G-code.
• Recommended software: Cura (popular, wide compatibility with printers).
• Note: Prusa printers work better with their specific slicer software.

Steps to Set Up Cura

1. Download and Install Cura

   • Find Cura via the Ultimaker website or Google search.
   • Accept user agreement after installation.

2. Add Your Printer

   • Select printer model (e.g., Creality Ender 3).
   • Use default profile settings for simplicity.

3. Explore Default Settings

   • Quality, infill, material, support, build plate adhesion.
   • Use the drop-downs to see and adjust settings.

Finding Models to Print

• Common file types: STL and 3MF (available from sites like Thingiverse).
• Start with simple models (e.g., calibration cube) to ensure successful prints.

Importing Models into Cura

• Use the folder icon to open STL files.
• Center the model if necessary.

Model Manipulation Tools in Cura

• Move: Adjusts position on the print bed.
• Scale: Changes size of the model.
• Rotate: Alters the orientation of the model.
• Mirror: Flips the model.
• Block Supports: Prevents supports in certain areas.

Print Settings Configuration

1. Nozzle and Filament

   • Specify nozzle size (e.g., 0.4mm) and filament type (e.g., PLA).

2. Quality Settings

   • Layer height affects print speed and detail (recommended 0.1 to 0.3mm for a 0.4mm nozzle).

3. Infill Settings

   • Strength of model determined by infill density (20% for calibration cube).
   • Default infill pattern: cubic.

4. Material Settings

   • Printing temperature: 180-210°C for PLA (default 200°C).
   • Build plate temperature: 50°C recommended.

5. Support Settings

   • Enable if model has overhangs (supported in red).

6. Build Plate Adhesion

   • Options include skirt, brim, and raft (use brim for better adhesion).

Slicing the Model

• Click Slice to generate G-code.
• Preview the print layers and save the output file.
• Tips for naming files: Shorter names and include settings details.

Transferring G-code to 3D Printer

• Save G-code to micro SD card (root directory).
• Insert SD card into printer and select the file to print.
• Ensure the correct temperatures are set before printing.

Troubleshooting

• If the file doesn't appear, reseat the SD card or shorten the file name.
