Coolant System: Water Level and Flow Rate¶
The Neon requires a constant flow of water to dissipate the heat generated by the laser. If the water is not circulating correctly, the flow sensor will prevent the laser from firing to avoid permanent hardware damage.
1. Checking the Water Level¶
The first step in troubleshooting circulation issues is verifying the reservoir.
- Status Check: Look at the sensor panel in Due Studio. The Water Level indicator should be OK.
- Solution: If the level is low, fill the reservoir until it is completely full.
2. Monitoring Flow Rate (Flow Sensor)¶
The Flow Rate indicates the strength of the water circulation through the tube.
- Optimal Flow: 100%.
- Critical Flow: Below 70%. If the flow drops below this threshold, the machine will stop for safety.
Common Causes for Low Flow:¶
- Kinked Hoses: Check if any silicone hoses are bent or "strangled" behind the machine or near the pump.
- Pump Failure: Click the Pump Icon (drop icon) in Due Studio to manually trigger the pump. Listen for the motor and watch if the flow reaches 100%.
3. Advanced Calibration (Software Adjustment)¶
If you have verified that the pump is working and hoses are clear, but the flow still reads below 70%, you may need to adjust the sensor multiplier via the web interface.
- Find the Neon's IP address (e.g., 10.2.2.1) by hovering over the connection icon in Due Studio.
- Enter the IP in your web browser.
- Navigate to Settings > Sensor Adjustments.
- Adjust the Flow Multiplier incrementally until the reading reaches 10 (do not exceed this value).
Safety Warning
Never operate the Neon if the water is not visibly moving through the laser tube, regardless of what the digital sensor displays.
Still experiencing low flow? If the flow remains low after these steps, there may be a blockage inside the tube or a faulty pump. Contact Due Laser Support immediately.
