After building an enclosure for my DIY CNC (Arduino Uno + CNC shield) I bought an NVR (no voltage release)switch to be able turn my Makita router on and off safely from outside the enclosure.

However, everytime the NVR switch is pressed it leads to a limit switch being triggered and UGS entering an alarm state. There is no wiring between the router and Arduino.

Some observations:

- The limit switches will trigger even if the router isn’t plugged into the NVR. The router just needs to be nearby.
- I can take the router out of the enclosure and move it some distance away from all CNC electronics and using the NVR switch will still trigger the limit switches.
- I’ve tried the NVR on different plug sockets and no change.

Has anyone had similar issues or can think of a way to solve this issue? Any help would be appreciated.
Cheers!
