Does your machine disconnect in the middle of a job? You may be experiencing interruptions because of electromagnetic interference (EMI) and static from a dust collection and vacuum system, causing the Arduino in your control box to freeze up momentarily. Instructions on how to ground your dust collection can be found at the resource below.
This method is a starting point, as every person’s setup is different - you may need to modify this to fit your needs. For example, using copper wire on both the outside and inside of your tube/hose may be necessary if you are using a high power vacuum which generates a lot of static.
