BLTouch self-start enable after Zmoves down by 10mm

Hi,

I am using BLTouch.

I am using MKS Gen V 1.4 + TFT3.2".

This TFT is having 'Print resume after power outage'. So, whenever the power comes, the print can be resumed.

Now I have added BLtouch to our machine. It is working finely. But, at the middle of the print, power goes and when it comes back, BLTouch is doing the selftest. At that time, the BLTouch is just above the print and the probe comes down and it hits the print. Due to this, it creates an error and the print is unable to resume.


I wanted to enable the BLTouch self test only when Z is moving 10mm down. I am using Marlin-1.1.x.

Thanks

The self test is nothing to do with marlin, its just somtthing the bltouch does when power is applied.
What is causing the power outage would be my concern.
