I have just installed a SKR Mini E3 V3 board ansd a BL touch clone.

Trying to set offset. 

Start with M851 Z0

now home printer 

M28 

This is where all the problem occurs, X & Y OK

z homes the start decendin to the bed and will not stop

I have taken the Z stop off as using bltouch as z stop.

How to i solve this problem
