Quick Start
-
Flash Klipper to the Octopus Pro (see docs/wiring.md)
-
Wire the board according to the pin assignments in docs/wiring.md
-
Copy config files to your Pi:
scp klipper/*.cfg pi@192.168.86.20:~/printer_data/config/ -
Update serial port in
printer.cfg:ssh pi@192.168.86.20 ls /dev/serial/by-id/* # Edit printer.cfg with the correct serial ID -
Restart Klipper and verify connection
Key Differences from Original Setup
| Setting | Original (Azteeg X3) | New (Octopus Pro) |
|---|---|---|
| MCU | ATmega2560 (Arduino) | STM32F446 |
| Pin format | ar## aliases |
Direct STM32 pins |
| Communication | FTDI USB-Serial | Native USB |
| Voltage reference | 5V ADC | 3.3V ADC |
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
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
