I recently installed a water cooled spindle on my OpenBuilds 1500. Now as soon as I touch the magnet to the spindle the Touch Probe Plus lights up, without any contact with the Probes plate. Even if I disconnect the control cable from the spindle. Anywhere on the gantry will trigger the probe. I've attached a video. Any help would be greatly appreciated. https://youtube.com/shorts/2qUyl7vqXfI?si=K8JfRpagoBHWPyJi
AC Earth to DC GND short circuit somewhere in your setup. Unplug things one at a time to find the source of the short then fix it.
