UNSOLVED CNC grounded 3Kw spindle probe

Hello everyone! i have been using the duet2 wifi for 2 years now on my delta and it works amazing never had any issues, you've done an amazing job both hardware and software wise, i have another laying around so i decided to try and use it for my home built cnc and probably upgrading to duet3 after, the problem is i'm afraid of burning something because i'd like to use a touch probe on my spindle but it is grounded, i'm afraid that by connecting the clip to the endmill it might hurt something on the duet since i'd be connecting the z_probe, 3.3v or GND pin to earth, can you advise on how i should proceed wiring wise ? do i connect the duet ground to the spindle so to earth, or the z_probe in or ..?
thanks a lot !
