Panel & Offline Operation

• Offline processing: run .OUT files from onboard memory or FAT32 U‑disk; maximum 500 stored files.
• Multi‑layer processing parameters: adjust laser power, speed, gas assist; real‑time modify power/speed during processing; frame preview, single‑axis jog movement.
• Administrator password protection: parameter backup / restore / factory reset / time‑limited machine lock.
• Rotary‑knife module: support manual & auto tool‑setting, spindle & press‑roller control, quick switch between laser‑cutting and rotary‑knife‑cutting mode.

Common Troubleshooting

1. Power‑on reset failure: inspect 24V power supply, short‑circuit in wiring, mainboard hardware damage.
2. Abnormal laser output: check PWM polarity setting, water‑protection signal, laser power supply configuration.
3. PC communication failure: verify USB driver, device ID, grounding; keep PC and controller within same Wi‑Fi network segment.
4. U‑disk access error: format U‑disk to FAT32 standard.
5. Out‑of‑working‑area alarm: correct machine dimension parameters, reset origin positioning point.
