Buttons and Indicator Lights
Button Operations
| Button | Short Press | Long Press |
|---|---|---|
| Channel 0 Forward | Start or stop channel 0 moving forward | Force channel 0 to move forward, stops when released |
| Channel 0 Reverse | Start or stop channel 0 moving backward | Force channel 0 to move backward, stops when released |
| Channel 1 Forward | Start or stop channel 1 moving forward | Force channel 1 to move forward, stops when released |
| Channel 1 Reverse | Start or stop channel 1 moving backward | Force channel 1 to move backward, stops when released |
| Status Button | Toggle load/automatic mode | Press and hold for about 2 seconds to perform sensor calibration |
Long-pressing a button temporarily ignores the normal sensor edge stop condition and is intended only for clearing the filament path when sensor anomalies are confirmed. Before operating, make sure the filament path is clear and keep fingers and tools away from pinch points, feed wheels, and motors. After releasing the button, confirm that the mechanism has stopped. Do not use this feature for extended periods during printing.
Device Modes
| Mode | Status Button | Purpose |
|---|---|---|
| Load Mode | Red | Manual loading, unloading, maintenance, and troubleshooting |
| Automatic Mode | Green | Automatically feeds and reloads filament based on buffer position |
Briefly press the status button to switch between the two modes. After switching, first observe the status light, then test individual channels.
In the paused (load) state, the status button, channel direction buttons, and indicator lights on both sides of the channel all show red, as shown below:
Channel Indicator Lights
| Light Pattern | Meaning |
|---|---|
| Red or red breathing | No filament detected in the channel |
| Green or green breathing | Filament detected in the channel |
| Green flashing | Channel is operating as the active channel |
| Yellow flashing | Button is controlling the channel moving forward |
| Blue flashing | Button is controlling the channel moving backward |
Status Button
The status button is used to toggle between load/automatic mode and to start sensor calibration. Buzzer notifications are described separately in the "Buzzer" section below.
Before performing any checks involving the filament path, wiring harness, terminals, or sensor installation listed in the table, completely turn off the printer and disconnect the power supply. Do not plug or unplug wiring harnesses or touch terminals while the device is powered on.
| Light Pattern | Meaning | Recommended Action |
|---|---|---|
| Green | Automatic mode | Verify the buffer and filament path are normal before use. |
| Red | Load mode | Used for manual loading, unloading, or troubleshooting. |
| White flashing | Not calibrated | Clear the filament path and perform sensor calibration. |
| Red, green, blue cycling | Calibration or saving calibration data in progress | Wait for the light pattern to finish; do not power off or operate motors. |
| Red fast flashing | Motion timeout or error state | Stop feeding, power off, and check the filament path and sensors. |
| Purple or purplish | Sensor wiring, installation, or input state may be abnormal | Stop automatic feeding, power off, and check the wiring harness and sensor installation. |
Calibration and error light patterns take priority over normal mode light patterns. If the alarm persists, first check the filament path and sensors; do not bypass the alarm by disabling protection.
Buzzer
The buzzer provides audible notifications only and does not affect mode switching or calibration functionality of the status button. If the beep parameter in the tool is set to 0, the device may not emit the following notification sounds.
| Sound Pattern | Meaning | Recommended Action |
|---|---|---|
| Repeated short beeps | Corresponding channel is out of filament | Confirm filament has reached the inlet sensor position. |
| Short, short, short, long | Motion timeout or distance protection triggered | Stop feeding and follow the troubleshooting process; do not disable protection. |
