I too am having this issue as well

I am using a BL Touch clone, unsure of which type and version, it's a black plastic casing.

My clone was working perfectly fine with the stock E3P board but now it does exactly as described by this ticket.

I was able to get it to probe 20 out of 25 points by forcing it to probe the Y axis first.

It seems to run into an issue when attempting to probe the right side of the bed, and I've adjusted firmware bounds settings to attempt to fix that to no avail.

I suggest disabling multiple probes //#define MULTIPLE_PROBING 2 and uncomment

define DELAY_BEFORE_PROBING 100

define PROBING_FANS_OFF

You could also try changing the probe points to 16. // Set the number of grid points per dimension.

define GRID_MAX_POINTS_X 4

define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X

I was able to figure out why mine wasn't finishing probing.

My BL Touch is x-38.15 and y-7.2 but my min probe edge was set to 20mm. I set MIN_PROBE_EDGE to 40 and I was able to get it to probe my entire bed successfully.

Hopefully this helps!

Thanks it works. I've a TouchMi But i'm sure there is a bug somewhere
