Step-by-step checks for power, connectivity, camera, optical path, motion, focus, and alarm issues.
Find the problem you are seeing below. Problems are grouped by type, and each group opens on its own page.
| Symptom | Check First |
|---|---|
| Cannot power on | Check power cable, emergency stop switch status, switching power supply indicator light, measure motherboard power cable voltage |
| Control screen not displaying | Check control screen for physical damage, check motherboard cable connections, confirm firmware version |
| Connection failed | Check baud rate, Type-C cable port, computer USB port, CH340 driver |
| Camera malfunction | Check computer camera permissions, camera cable connection, verify camera output |
| Power degradation | Check focal distance, software parameters, light path verification, clean reflector and focusing lens |
| Blurry engraving | Check focal distance, clean reflector and focusing lens, ensure material is not shifting |
| Homing failed | Check motor status, limit switch status, firmware version |
| Distorted engraving pattern | Check timing belt tension, X/Y axis synchronous wheel screws, X-axis parallelism |
| Unclosed engraving lines | Check focal distance, engraving parameters, focusing lens, light path; enable constant power, adjust minimum power value |
| Engraving stops midway | Confirm alarm message, check Type-C cable, computer port, try different software |
| Alarm: travel limit reached | Confirm if limit switch was triggered, check limit switch status, firmware version |
| Auto-focus failed | Check material properties, upper/lower limit switch status, Z-axis motor status |
| Flame alarm | Check working environment, line density, engraving material, adjust sensitivity |
| APP connection failed | Confirm WiFi mode is enabled, WiFi name is searchable, turn off mobile data, try a different phone |
