    Only if you think there's a chance this code might eventually get pulled into the fork or "official" Marlin. As it is now, if someone wants to use it, they'll copy it in as it stands. My changes were for those who wanted to add the code, but not use it. A pretty small population I'd think.

    I should have noticed the missing ;. I'm in the middle of a print right now, so I'll test how it prints out the matrix later.

    Nope, heat makes it flex and the parts expand and when it cools down, plus the movements of the bed while it is warm, makes the parts change ever so slightly.

    To see if your printer will work do a G28/G29 U 6 T with everything heated up. Now go do a print of something like normal. Let it all cool down and in 1 hour come back to a nice room temp printer. Now with the complete printer sitting there at room temp go heat up the hotend and bed then do a g28/g29 U 6 T and see if the numbers are exactly the same. If they are then you have a golden printer and should never need to do another G28/G29 again.

    So you think nobody should ever use this code?

    No, of course not. (If this was directed at me???) I just don't know that I'm going to use it much because my printer isn't good enough to hold super tight tolerances across a big range of temperatures. But some people really do have machines that can benefit from this.

    Exactly what I was getting at, or trying to say, AbuMaia.

    For most people, not the lucky few, this routine will mean they can print in multiple colors in one session with a single extruder but once that printer cools down and you have to reheat it those people, the majority of the people that includes me, and apparently Roxy is among us, we *must* reissue the G28/G29 again.

    I don't think anyone is saying this will be a one-time set-and-forget feature. Why do you think I went to find a way to run a G29 from the LCD on a standalone printer?

    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???

    Maybe take out one of the \n before Bed Level Correction Matrix, to get rid of that first blank line?

    edit: I forgot I already took one out. Taking out the second and remaining \n gives this:

    echo:Bed Level Correction Matrix:
    1.000000 0.000000 -0.000053
    -0.000000 1.000000 -0.000038
    0.000053 0.000038 1.000000

    I didn't like the 'echo:Bed' so I went back and put in a space before Bed, now it's:

    echo: Bed Level Correction Matrix:
    1.000000 0.000000 -0.000053
    -0.000000 1.000000 -0.000038
    0.000053 0.000038 1.000000
