Many issues after upgrading to 3.0 RC-12

my endstop for X is actually too far off the bed.
You can also use a negative value for your M208 X minima such that 0 is the edge of the bed and the negative value is when the endstop is triggered.

Ok, this did the trick perfectly, now the nozzle is lined up with the corner of the bed. Thank you!
Next issue..... When I run my G29 it skips the back half of the bed entirely. I suspect I have something set wrong with the offsets or mesh config but I must not be understanding the math correctly

Make sure your probe offset is correct. -X to the left, +X to the right. -Y to the front, +Y to the back.

Ah ok, that was wrong. my probe is front right of the primary nozzle, so i changed it now to read y-5
Still having the same issue, back third of the bed will not probe

That looks like a mistake - Y300 right??
-
Yeah that seems to have been it. I was using the RR config tool and I don't think it filled in any of this stuff correctly. I set my maxima for XYZ now correctly and ran the probing again and it seems to have worked.
One more thing - on my RR 2 FW the BLTouch only probed each spot 1 time, now it does it like 4 times. Is this a setting somewhere?
Also wondering on the correct way to do start Gcode with mesh enabled. I have this:
G29 S1 ;Load heatmap G28 G1 Z15.0 F7000 ;Move the platform down 15mm G92 E0 G1 F200 E3 G92 E0 G1 X150 Y150 F7000 ; Move Probe to middle of bed G30 ; Do a single probeShould I change anything?

Yes, see the documentation for M558.
-
Got it - I just noticed this error after starting a print
Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset.
I am watching the Z motor and it seems to be adjusting as the head moves around though.

So I read this and I am still a little confused why it's happening - because I did this:
"Move the nozzle over the centre of the bed and do a single G30 probe (G30 without parameters)."
The center of bed G30 is in my start gcode for each print.The only difference that I did not do is run the G29 while the printer was hot. Is this the reason the error is coming up?
