Hey JP,

I second @SkyKam. The usual cause of such a problem is that the closing of the electrical circuit, [which must happen to achieve probing with a touch probe](https://forum.onefinitycnc.com/t/replacement-curly-cable/14837/7), does not happen cleanly. Either the surface of the bit, the touch probe or the magnet probe is not properly conductive (dust, grease, corrosion), or you have a bad contact in the cable or in the connector of the touch probe/magnet probe.
