Saving G29 Bed Level Correction Matrix to EEPROM

[AbuMaia]

Now that we have this mod to save the G29 matrix for an entire print session (or longer), it is no longer necessary to add a G29 to the start gcode when slicing. However, those of us who run our printers standalone, we need another way of running the G29 when we change a setting or a glass plate. I believe that many who run their printer standalone have an LCD display on their printer. Here's what I did to add G29 to the LCD menu:

In ultralcd.cpp, find MENU_ITEM(gcode, MSG_AUTO_HOME, PSTR("G28"));
Just after it, add MENU_ITEM(gcode, MSG_BED_LEVEL, PSTR("G29 n5"));

In language.h, find #define MSG_ENDSTOP_ABORT "Endstop abort"
Just after it, add #define MSG_BED_LEVEL "G29 Bed Level"


Roxy, I ran into an error adding your code:

ConfigurationStore.cpp: In function ‘void Config_PrintSettings()’:
ConfigurationStore.cpp:129:65: error: void value not ignored as it ought to be
plan_bed_level_matrix.debug("\n\nBed Level Correction Matrix:")
^ (this caret should be under the closing parenthesis after "Matrix")

That is the only error. Commenting out only the added code block from Config_PrintSettings let it compile cleanly.

It's fixed now. Somehow during the Cut & Paste I didn't get the very last character of the line (which was a semi-colon. The compiler knows it is missing a semi-colon, can't it just put it in there for me???

Any way, if you go add the semi-colon it should compile clean and let you print out the Bed Level Correction Matrix. I'm not sure how the output is going to look because I can't run any of this code yet to test it.

AbuMaia, does the code behave as expected and do what people wanted? Can you add the semi-colon and invoke the EEPROM Print so we can check if the matrix prints OK ?

So I suspect we need a blank line (or one that just says echo after the last line of the matrix. But I kind of hate to add blank lines of output. Opinions anybody???

However, those of us who run our printers standalone, we need another way of running the G29 when we change a setting or a glass plate.

Just after it, add MENU_ITEM(gcode, MSG_BED_LEVEL, PSTR("G29 n5"));

In language.h, find #define MSG_ENDSTOP_ABORT "Endstop abort"
Just after it, add #define MSG_BED_LEVEL "G29 Bed Level"

I added this and it was working fine. Had a show yesterday and it didn't work anymore.
Got this message. When I do a g29 n5 in Repetier it works fine. Any ideas?

Thank you works awesome just need to "Auto Home" prior to G29
