[BUG] Incorrect total count when probing for leveling

[jan-gerard]

Bug Description

When probing less than the maximum number of points for bed leveling, (e.g. G29 P3, while I have defined #define GRID_MAX_POINTS_X 5), the display says still Probing Point 1/25, while it should say Probing Point 1/9.

My Configurations

#define MULTIPLE_PROBING 3
//#define EXTRA_PROBING    1
#define AUTO_BED_LEVELING_LINEAR
#define GRID_MAX_POINTS_X 5
#define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X

Steps to Reproduce

1. Set #define GRID_MAX_POINTS_X 5 in Configuration.h
2. Compile and upload firmware.
3. Level bed with G29 P2.

Expected behavior:
Probing Point 1/4 ... Probing Point 2/4 ... Probing Point 3/4 ... Probing Point 4/4 ... done.

Actual behavior:
Probing Point 1/25 ... Probing Point 2/25 ... Probing Point 3/25 ... Probing Point 4/25 ... done.

Additional Information

I think that line 702 in G29.cpp should be changed from
ui.status_printf_P(0, PSTR(S_FMT " %i/%i"), GET_TEXT(MSG_PROBING_MESH), int(pt_index), int(GRID_MAX_POINTS));
to
ui.status_printf_P(0, PSTR(S_FMT " %i/%i"), GET_TEXT(MSG_PROBING_MESH), int(pt_index), int(abl_points));

...and line 700 into
if (verbose_level) SERIAL_ECHOLNPAIR("Probing mesh point ", int(pt_index), "/", int(abl_points), ".");

[jan-gerard]

I tested this change, and now it works perfectly.

maybe submit a PR with the fix?

@jan-gerard can you attach your configuration files, as required by the issue template? Ideally these would be updated to work with the bugfix-2.0.x branch.

There isn't enough information in your description for somebody to easily reproduce this. For example, it does not indicate which bed leveling mechanism you are using. Providing your configuration files will ensure that anybody looking at this is configured exactly the same way you are.

Thanks for the patch! It was a cinch to locate and to apply, and makes it in just under the wire for 2.0.6….

This patch seems to break compiling with AUTO_BED_LEVELING_BILINEAR, as abl_points nether declared nor has it a value...
Maybe the comment in line 248 of G29.cpp is somewhat misleading:

#elif ENABLED(PROBE_MANUALLY) // Bilinear

Re-opening, since the "fix" for this broke builds.
