+# 🧹 Cleanup Notes - user_settings_clean.cfg
+
+## What Changed
+
+### ✅ Renamed to Standard Names
+- `PRINT_START_NOCCI` → `PRINT_START` (now active)
+- `PRINT_END_NOCCI` → `PRINT_END` (now active)
+
+### ✅ Removed Unused Code
+- `CLEAN_NOZZLE_OLD` - KNCM handles nozzle cleaning
+- `CLEAN_NOZZLE_WHILE_PRINT` - Not needed
+- All commented-out git update macros
+- Duplicate `[bed_mesh]` sections
+- Commented-out `[probe]`, `[scanner]`, `[mcu scanner]` sections
+
+### ✅ Reduced Comments
+- Removed excessive inline comments
+- Kept essential documentation
+- Added clear section headers
+- Removed redundant explanations
+
+### ✅ Kept as Reference (commented but useful)
+- Old probe config (in case you need to revert)
+- Alternative ADXL configs
+- Old scanner configs
+
+### ✅ Structure
+- Organized into logical sections
+- Clear section headers
+- Consistent formatting
+- Easy to read and maintain
+
+## File Comparison
+
+| Metric | optimized_user_settings.cfg | user_settings_clean.cfg |
+|--------|----------------------------|-------------------------|
+| **Lines** | ~430 | ~240 |
+| **Comments** | ~120 | ~40 |
+| **Active Macros** | 2 (PRINT_START_NOCCI, PRINT_END_NOCCI) | 2 (PRINT_START, PRINT_END) |
+| **Helper Macros** | 4 | 4 (QUICK_TOUCH, CALIBRATE_PROBE, BABYZ_±) |
+| **Unused Code** | ~80 lines | ~0 lines |
+
+## Migration
+
+### Option A: Use Clean Version (Recommended)
+```bash
+cd ~/printer_data/config
+cp user_settings.cfg user_settings.cfg.backup-$(date +%Y%m%d)
+cp open4neptune-new/user_settings_clean.cfg user_settings.cfg
+# Restart Klipper
+```
+
+### Option B: Keep Current
+- Your current `optimized_user_settings.cfg` still works
+- Just more verbose with comments
+
+## Testing
+
+After switching to clean version:
+```gcode
+; Test PRINT_START
+PRINT_START EXTRUDER_TEMP=200 BED_TEMP=60
+
+; Test PRINT_END
+PRINT_END
+
+; Test helpers
+QUICK_TOUCH
+BABYZ_PLUS
+BABYZ_MINUS
+```
+
+## Notes
+
+- **No functional changes** - only cleanup and renaming
+- **All features preserved** - Cartographer, KNCM, Calibration Suite
+- **Backwards compatible** - same macro names as stock Open4Neptune
+- **Easier to maintain** - less clutter, clearer structure
+

+**Created:** 2026-03-12  
+**Purpose:** Clean, production-ready user_settings.cfg  
+**Size:** ~45% smaller than optimized version
