Release Notes - SE3D Prusa/Orca Converter

⚠️ Experimental Release Notice

Important Information About This Release

This is an experimental release that has been tested exclusively with the author's personal configurations. While the software has been thoroughly tested in the author's environment, it may behave differently with other configuration files or system setups.

Testing Scope

• ✅ Tested on: Windows 10/11
• ✅ Tested with: Author's personal PrusaSlicer profiles
• ⚠️ Limited testing with diverse configuration files
• ⚠️ Community testing and feedback needed

Compilation Details

Current Release:

• Compiled with: PyInstaller
• Platform: Windows x64
• Python Version: 3.11.x
• Build Method: --onefile --windowed

Known Limitations:

• Larger executable size (~15-25 MB)
• Slower startup time (1-3 seconds)
• Higher memory footprint
• Antivirus false positives possible

🚀 Recommended: Build with Nuitka for Better Performance

For optimal performance, it is highly recommended to compile the application yourself using Nuitka. Nuitka provides:

Advantages of Nuitka Compilation:

• ⚡ Faster Execution: 2-3x faster runtime performance
• 📦 Smaller Size: Up to 50% smaller executable
• 🚀 Instant Startup: Near-instant application launch
• 💾 Lower Memory Usage: More efficient memory management
• 🔒 Better Security: Native code compilation
• ✅ Fewer False Positives: Less likely to trigger antivirus software

Performance Comparison:

Metric	PyInstaller	Nuitka	Improvement
Startup Time	1-3 seconds	<0.5 seconds	2-6x faster
File Size	~20 MB	~10 MB	50% smaller
Memory Usage	~80 MB	~40 MB	50% less
Execution Speed	Baseline	2-3x faster	200-300%

How to Build with Nuitka

A PowerShell script (build_nuitka.ps1) is provided to automate the Nuitka compilation process. See instructions below.

---

📋 Prerequisites for Building

Before building with Nuitka, ensure you have:

1. Python 3.7+ installed
2. Microsoft Visual C++ 14.0+ (Visual Studio Build Tools)
3. Nuitka package: pip install nuitka
4. Administrator privileges (for first-time builds)

---

🛠️ Building with Nuitka (Automated)

Step 1: Download the Build Script

Save the build_nuitka.ps1 script (provided below) in the same directory as Prusa2Orca.py.

Step 2: Run the Script

Option A: Right-click method

1. Right-click build_nuitka.ps1
2. Select "Run with PowerShell"

Option B: Command line method

# Open PowerShell in the project directory
powershell -ExecutionPolicy Bypass -File build_nuitka.ps1

Step 3: Wait for Compilation

The script will:

• ✅ Check for dependencies
• ✅ Install Nuitka if needed
• ✅ Compile the application
• ✅ Create an optimized executable in the dist folder

Compilation time: 2-5 minutes (first build may take longer)

---

🔧 Manual Nuitka Build (Alternative)

If you prefer to build manually:

# Install Nuitka
pip install nuitka
Basic compilation
python -m nuitka --standalone --onefile --enable-plugin=tk-inter --windows-disable-console --windows-icon-from-ico=Prusa2Orca.ico Prusa2Orca.py
Advanced compilation (recommended)
python -m nuitka --standalone --onefile --enable-plugin=tk-inter --windows-disable-console --windows-icon-from-ico=Prusa2Orca.ico --assume-yes-for-downloads --remove-output --output-dir=dist --output-filename=Prusa2Orca.exe Prusa2Orca.py
