# 📝 Changes for PRINT_START_NOCCI
|
|
|
|
## 🎯 Optimizations Applied (2026-03-12)
|
|
|
|
### Key Changes in `optimized_user_settings.cfg`:
|
|
|
|
| Line | Change | Reason |
|
|
|------|--------|--------|
|
|
| 5 | `SET_GCODE_OFFSET Z=0` added | Reset Z-Offset before every print (Cartographer best practice) |
|
|
| 9 | `G28` → `CG28` | Use Open4Neptune smart home command |
|
|
| 10 | `CARTOGRAPHER_TOUCH_HOME` added | Precise Z0 measurement with Cartographer sensor |
|
|
| 35-36 | Temp tolerance `±4-10°C` → `±2°C` | Tighter temperature control for consistent starts |
|
|
|
|

## 📋 Deployment Steps:
|
|
|
|
1. **Backup current config:**
|
|
```bash
|
|
cd ~/printer_data/config
|
|
cp user_settings.cfg user_settings.cfg.backup-$(date +%Y%m%d)
|
|
```
|
|
|
|
2. **Clone repo (if not done):**
|
|
```bash
|
|
cd ~/printer_data/config
|
|
git clone https://git.sky-net.it/nocci/open4neptune-new.git
|
|
```
|
|
|
|
3. **Copy calibration folder:**
|
|
```bash
|
|
cp -r open4neptune-new/calibration/ ~/printer_data/config/
|
|
```
|
|
|
|
4. **Copy optimized user_settings.cfg:**
|
|
```bash
|
|
cp open4neptune-new/optimized_user_settings.cfg ~/printer_data/config/user_settings.cfg
|
|
```
|
|
|
|
5. **Restart Klipper:**
|
|
- Via Mainsail/Fluidd: Machine → Restart Firmware
|
|
- Or SSH: `sudo systemctl restart klipper`
|
|
|
|
6. **Test calibration macros:**
|
|
```gcode
|
|
; In Mainsail Console:
|
|
CALIBRATION_MENU
|
|
```
|
|
|
|
7. **Test print** and observe:
|
|
- Check console for "Starting Print Sequence..."
|
|
- Verify Cartographer Touch Home runs
|
|
- Monitor temperature wait times
|
|
|
|
## 🔄 PRINT_END_NOCCI Update:
|
|
|
|
The optimized `PRINT_END_NOCCI` macro combines the best of both worlds:
|
|
|
|
**From printer.cfg:**
|
|
- ✅ `END_TUNE` beeper jingle
|
|
- ✅ Park position `X0 Y315` (better print visibility)
|
|
|
|
**From your custom version:**
|
|
- ✅ Detailed console/LCD messages
|
|
- ✅ `M84` to disable steppers
|
|
- ✅ Higher Z-park (10mm)
|
|
- ✅ Both lights turned off
|
|
- ✅ Filament sensors disabled
|
|
|
|
**To use it:** Update your slicer's end gcode to call `PRINT_END_NOCCI` instead of `PRINT_END`
|
|
|
|
## 🔧 What This Improves:
|
|
|
|
- **Better Z accuracy** with Cartographer Touch Home
|
|
- **Consistent Z-Offset** reset before each print
|
|
- **Tighter temperature control** (±2°C vs ±4-10°C)
|
|
- **Smart homing** with CG28 (skips if already homed)
|
|
|
|
## ⚠️ Notes:
|
|
|
|
- Keep `printer.cfg` untouched (Open4Neptune updates will overwrite it)
|
|
- Only `user_settings.cfg` contains your customizations
|
|
- Backup before Open4Neptune updates!
