GRBL Errors: Alarm 2

Being able to effectively diagnose and correct any errors with your laser will help ensure minimal frustration and time loss. For lasers running GRBL firmware, Alarm 2 is the most common error we see. This is a soft limit error, that occurs when your laser is sent a move command that would cause it to go out of bounds. In this video we cover the different ways it is triggered, and how to resolve this issue.
