There is a huge amount of work that has been done to identify which 'clone' you have and how it should be set up.

But we do have the real BL-Touch probes working perfect!!!! It is the 'clones' that are having problems.
I bought my BL Touch from Colin at Makerfarm.

I got it working, and was having issues with the probe speed.
