Re: Router spindle electrical noise.

Is your limit sensing loop AC or DC, you could place an capacitor
across the lines as the go back into the control to try to snub the
induced noise. Try a .22uF to start, the larger the value, the more
snubbing, but the response to limits time will be reduced.

Also try one of the AC line filters on the voltage going to the
router.

Describe your setup more withe repsect to what breakout or control you
are using.
