Hi,

I orginally purchased the probe back in July 2017 (SMD sensor) and it's been working well.

I did a swap from an MKS Gen 1.4 to SKR 1.3 and it seems since about that time the sensor has gotten very sensitive (I thought it might of been before I did the swap as I did get the occasional high z trigger). Above 20mm from an object (depends on surface) the LED may rapidly flash with no rhythm, give a couple of flashes or sometimes it will 'behave'. Below 20mm the the probe will behave normally (although it might briefly flash just above trigger point then turn solid).

I'm measuring 4.8v between the hole near D2 and L1.

If I measure VCC and Out it comes up at 4.25v and 0.32v triggered.

I'm thinking I've managed to kill the sensor somehow, but unsure if there is something I've missed!
