Introduction
This post is part of the CNC Mill Concept hub. It explicitly documents features and concepts that are not part of the current build, to prevent scope creep and preserve design intent for later development phases.
Motion and Feedback Upgrades
- Closed-loop servo drives on linear axes
- Dual-loop control using external feedback
- Glass scale integration for linear axes
- Replacement of stepper-based motion system
Drive Electronics
- Custom servo inverter development
- Evaluation of GaN, SiC, or IGBT-based power stages
- Unified drive hardware for multiple machine projects
Additional Axes
- 4th axis integration
- 5th axis integration
- Simultaneous multi-axis machining capability
Advanced Compensation Strategies
- Thermal compensation of machine structure
- Advanced force-based compensation
- Higher-order compliance models
- Integration of additional observers
Manufacturing and Implementation
- Detailed CAD models
- Manufacturing drawings
- Assembly procedures
- Calibration procedures
- Validation and acceptance testing
Documentation Expansion
- Implementation-level documentation
- Firmware and software architecture documentation
- Maintenance documentation
- Operating procedures
