|
|
## Quick Start
|
||
|
|
|
||
|
|
1. **Flash Klipper** to the Octopus Pro (see [docs/wiring.md](docs/wiring.md))
|
||
|
|
|
||
|
|
2. **Wire the board** according to the pin assignments in [docs/wiring.md](docs/wiring.md)
|
||
|
|
|
||
|
|
3. **Copy config files** to your Pi:
|
||
|
|
```bash
|
||
|
|
scp klipper/*.cfg pi@192.168.86.20:~/printer_data/config/
|
||
|
|
```
|
||
|
|
|
||
|
|
4. **Update serial port** in `printer.cfg`:
|
||
|
|
```bash
|
||
|
|
ssh pi@192.168.86.20
|
||
|
|
ls /dev/serial/by-id/*
|
||
|
|
# Edit printer.cfg with the correct serial ID
|
||
|
|
```
|
||
|
|
|
||
|
|
5. **Restart Klipper** and verify connection
|
||
|
|
|
||
|
|

## Calibration Checklist
|
||
|
|
|
||
|
|
After wiring, perform these calibrations:
|
||
|
|
|
||
|
|
- [ ] Verify motor directions (invert DIR pins if needed)
|
||
|
|
- [ ] Check endstop triggering (`QUERY_ENDSTOPS`)
|
||
|
|
- [ ] Verify thermistor readings at room temperature
|
||
|
|
- [ ] PID tune extruders: `PID_EXTRUDER` / `PID_EXTRUDER1`
|
||
|
|
- [ ] PID tune bed: `PID_BED`
|
||
|
|
- [ ] PID tune chamber: `PID_CHAMBER`
|
||
|
|
- [ ] Calibrate Z endstop: `Z_ENDSTOP_CALIBRATE`
|
||
|
|
- [ ] Run bed mesh: `BED_MESH_CALIBRATE`
|
||
|
|
- [ ] Verify IDEX tool changes: `T0` / `T1`
|
||
|
|
|
||
|
|
## Useful Commands
|
||
|
|
|
||
|
|
```gcode
|
||
|
|
T0 # Switch to extruder 0
|
||
|
|
T1 # Switch to extruder 1
|
||
|
|
CALIBRATE_M2 # Full calibration routine
|
||
|
|
PID_EXTRUDER TEMP=250 # PID tune extruder at 250°C
|
||
|
|
PID_BED TEMP=110 # PID tune bed at 110°C
|
||
|
|
LOAD_FILAMENT # Load filament
|
||
|
|
UNLOAD_FILAMENT # Unload filament
|
||
|
|
```
