*Rep5x enables complex geometries without support structures through 5-axis printing*

## Overview

Rep5x democratises 5-axis 3D printing by creating an **affordable retrofit system** for consumer desktop 3D printers. The system adds two rotational axes (A and B) to standard XYZ printers, enabling:

- **Support-free printing** of complex overhangs
- **Improved surface quality** through optimal layer orientation  
- **Stronger parts** by aligning layer direction with stress patterns
- **Reduced material waste** by eliminating support structures

## Quick start

**For easier navigation, visit [Rep5x.com](https://rep5x.com) for the same guides in a more user-friendly format.**

### 1. Check hardware support
Currently supported printers:
- **Ender 5 Pro** - Working prototype
- **Ender 3 V3 SE** - Working prototype with full documentation

### 2. Get the files
- **3D printed parts**: `build-guide/printer-specific/[your-printer]/3d-printed-parts/`
- **Parts list**: `build-guide/universal-parts/bill-of-materials/bom-shared.md`
- **Assembly guide**: `build-guide/assembly-instructions-universal.md`
- **Firmware**: Use the [Firmware Builder](https://tools.rep5x.com/firmware-builder/) to generate custom firmware for your setup

### 3. Join the community
**Discord**: https://discord.gg/GNdah82VBg for build support and discussions

⭐ **Star this repo** to support open-source 5-axis printing development!

## Hardware support

| Printer model | Status | Documentation |
|---------------|--------|---------------|
| Ender 5 Pro | ✅ Working prototype | Minimal |
| Ender 3 V3 SE | ✅ Working prototype | Complete |
| Generic | Guidelines only | Complete |

## Features

### Current capabilities
- **Continuous C-axis rotation** (unlimited yaw movement)
- **>90° B-axis tilt** for complex geometries
- **Slip ring integration** prevents cable tangling
- **Modular design** for different printer platforms

## Roadmap

### Phase 1 (completed)
- [x] Ender 5 Pro working prototype
- [x] Ender 3 V3 SE adaptation
- [x] Complete documentation and assembly guide
- [x] Marlin firmware configuration
- [x] Setting up the Discord community
- [x] Community guidelines for new printer adaptations

### Phase 2 (current)
- [ ] Community testing and documentation feedback
- [ ] Support users building their first Rep5x systems
- [ ] Identify and fill documentation gaps
- [ ] Accelerate development through user contributions
- [ ] Additional printer model support based on community demand

### Community-driven development
The project's future depends on community involvement. We're focusing on enabling makers to:
- **Adapt to new printer models** with community support
- **Improve documentation** through collaborative contributions
- **Develop slicing features** as open-source solutions
- **Share builds and modifications** to help others
