When the indicator shows a solid red light, it suggests that LP4 has entered an Emergency Self-Locking Mode. This happens when the Emergency Stop Button is pressed.
Here's how the Emergency Stop Button (e-stop) looks:
Emergency Self-Locking Mode
The machine will shut off and any operations won't be viable in this mode.
Tips: Only press the Emergency Stop Button for urgent situations. Once the button is pressed, any ongoing engraving will be stopped.
Release from the Mode
To release from the Self-Locking Mode, please press the button again, the machine will then be restarted.
