Why doesn't 9x9 mesh probe the top right point?

[peeter-virk]

On the most recent build, the 9x9 bed mesh the last point won't be probed instead the probing finishes with
80 points probed.
printer: Ender3v2
board: one with the lowest number supported.
I used the precompiled code.

Probe offsets / HS mode

Most likely, your nozzle to probe X/Y combined with the mesh insert you have set combined with the physical max for Y don't allow the probe in that position. Smart Fill will auto generate a value for that position if you use it.

I've had this happen randomly. Running mesh again without changing anything usually succeeds. Not sure of the cause, but it has happened super rarely. Maybe twice out of ~50 times.

I, too, am running precompiled; Ender3S1-F4-UBL-20221222 in my case.

Turn off HS mode. If that doesn't fix it, check your cables. Put a ferrite ring to avoid electrical interferences.

I am using the CR probe mod to move it to [near] Y-offset = 0 (-1.8mm in the case of the Plus model). I have had it happen in both HS mode and normal mode, but I also have had none of the usual issues with HS mode on my Plus model.

I hadn't considered the possibility of eletrical interference, though. Quite possible since my probe wires have a lot more unfettered slack with the mod backplate and new probe position. I'll throw a ferrite bead on the line and keep an eye out for it to happen again. Who knows cuz I've only ever had it happen twice so far.
