Smart effector LED randomly turning on and off

gperman

Here's a vid of the LED's turning on and off. It appears as if the LED's turn off when the effector reaches a specific area. Possibly a stretched wire loosing electrical contact? Could it be the magnets? I alternated polarity for the arms that are closest near the smart effector.

Anyone else deal with this? Faulty board maybe?

Are the print cooling fans running? The magnetic fields from running fans can induce enough voltage in the effector electronics to trigger it.
