Marking Parameters Explained
The supplied manual identifies several important marking parameters. These settings should be changed according to the material and marking requirement rather than copied blindly from another job.
| Parameter | What It Controls | Practical Meaning |
|---|---|---|
| Marking Speed | Writing speed of the laser focus | Higher speed can reduce processing time but may change marking energy. |
| Jump Speed | Movement speed between marking vectors | Too much or too little can affect total cycle time and positioning behavior. |
| Power | Relative laser power | Higher value increases laser energy; the manual recommends not exceeding 90% during use. |
| Frequency | Laser pulse frequency | Changes the pulse behavior and therefore can affect the marking result. |
| Jump Delay | Delay after movement | Too short can create positioning artifacts; too long increases marking time. |
| Laser-On Delay | Delay before laser output | Incorrect setting can create poor vector starting points. |
| Laser-Off Delay | Delay after marking command | Incorrect setting can cause incomplete or burned vector ends. |
| Corner Delay | Corner processing timing | Needs to be matched with speed and the required marking quality. |
The manual specifically explains that delay parameters must be matched to jump and marking speeds. Excessively short or long delays can produce incomplete vectors, excessive heat/coking or longer marking times. :contentReference[oaicite:10]{index=10}
Production Line and Trigger Functions
Although this is a handheld machine, the supplied control system also contains functions for sensor-triggered and production-line marking.
Static Marking
Static marking can use jog mode or sensor/foot-switch mode. The manual describes foot-switch triggering in jog mode and sensor-triggered operation in sensor mode. :contentReference[oaicite:11]{index=11}
Flight Marking
Flight marking is intended for moving products. The system can use an encoder to synchronize with conveyor movement, or use a simulated line speed when an encoder is not enabled.
| Mode | Purpose |
|---|---|
| Normal Mode | Sensor-based marking with defined sensor distance. |
| Pipeline Mode | Marks products according to defined starting and spacing distances. |
| Continuous Mode | Repeated marking according to sensor state and configured spacing. |
