Do you have all 5 wires from the BLTouch connected to the board?
Thanks.

Yes Black and Brown connected to the same pin

I might be crazy but I ordered a new BL Touch, see if it acts the same?

It's possible that you have a defective one.
It's also possible that the existing one needs adjustment. I've never had to do it but I understand there is some sort of adjustment that sometimes needs to be made.

Can you explain that issue again? What exactly is it doing and what are you doing? Video?
-
@phaedrux When homeall, or when G30, the Z axis lowers the BL Touch until it come into contact with the bed surface. the BL Touch once in contact with the bed, it retracts as it should. The Z axis keeps descending as the BL Touch trys to extend the probe again. It cannot extend so it errors and try's to drive the BL Touch through the Bed.
-
So the Z axis never actually stops?
I dunno if this has been linked yet, but this is the safe way to test the probe.

@phaedrux I did go through that but couldn't get past this part. I think I am going to wait and see if a new probe works. Thanks for all your help, I will let you know if new probe make a difference.

I ordered a new BL Touch, installed it and now works perfectly. Looks like it was defective all along.

Well by now you have probably learned everything you needed to know about BLTouch units.
Glad it is working.

@fcwilt That is for sure

Bltouch is the kind of thing that it pays to have a spare for. Always buy two. They work great most of the time, but the pins are fragile (I bent one just today!) and the wiring can be fragile too. Having a spare to sanity check is a big help.
