Still can’t get G32 to work properly.

3D printer type: CoreXY; controller: Azteeg X5 Mini v1.0, Windows 10, Repetier Host v2.2.4, PrusaSlicer 2.40
Hi everybody. I have been trying to upgrade to automatic bed
leveling, but I’ve been having a few problems. Last week on this
forum I asked a question about why, after executing a G32, I was
getting an error message: “No strategy found to handle G32”. My
question was kindly answered that I should update my firmware.bin
file, which I did. Thankfully I am no longer getting the error
message, but now, when I do a G32, the carriage now does a rapid move
to the left and hits the X axis limit switch.
My 3D printer is a CoreXY (build volume 290x290x300) with an Azteeg
X5 mini v1.0 controller from Panucatt.com. The 3D printer has been
running very well for almost a year. The machine zero is in the lower
left corner. The probe is 25mm to the right of the nozzle. I know
that the distance is exactly 25mm positive in X because I have my
complete 3D printer in CAD (including the Touch MI and its mount).
Therefore, in my Config.txt file, I entered the offset for the the
z-probe as:
leveling-strategy.rectangular-grid.probe_offsets 25,0,0 #
Optional probe offsets from the nozzle or tool head - Z Always zero
I don’t want the G32 to probe starting at X0, Y0. I would prefer
that the probe would probe a grid from X25, Y25 to X240 (290-25-25
for the probe offset), Y265 (290-25) with 7 probe points in both the
X and Y.
So I have 3 questions:
1) How do I stop the G32 command from crashing the carriage into the
Xmin limit switch? Can I specify the above coordinates in the G32
line of code?
2) How do I correctly specify the start coordinates and size of the
grid? Presently, I have entered the following in my Config.txt file:
# associated with zprobe the leveling strategy to use
leveling-strategy.rectangular-grid.enable true # The strategy must be enabled in the config, as well as the zprobe module.
leveling-strategy.rectangular-grid.x_size 280 # size of bed in the X axis
leveling-strategy.rectangular-grid.y_size 290 # size of bed in the Y axis
leveling-strategy.rectangular-grid.grid_x_size 7 # The size of the grid, for example, 7 causes a 7x7 grid with 49 points.
# Must be an odd number.
leveling-strategy.rectangular-grid.grid_y_size 7
leveling-strategy.rectangular-grid.do_home true
leveling-strategy.rectangular-grid.probe_offsets 25,0,0 #
Optional probe offsets from the nozzle or tool head - Z Always zero
leveling-strategy.rectangular-grid.save false # If the saved grid is to be loaded on boot then this must be set to true leveling-
strategy.rectangular-grid.initial_height 10 # will move to Z10 before the first probe
leveling-strategy.rectangular-grid.human_readable true # Human readable formatting of probe table
3) After reading an article at:
(http://smoothieware.org/pcb-milling),
I wondered if it might be easier if I used:
leveling-strategy.rectangular-grid.only_by_two_corners true
If I use this strategy, would I have to erase the whole (leveling-strategy.rectangular-grid-xxxx) section?
I know the Touch Mi is working and is detected properly by my controller (by checking it with an M119). Also, G30 works fine, reporting values in Z (example: Z22.2725 C:8909)
Anyway, my config.txt file can be read at:

Any help would be appreciated.
