    Problem second print Bl touch

    Hi everybody


    I have a problem with my Bltouch: I have read a lot of articles and it is far from simple;


    to launch the first print:
    g28;
    G29;
    m500;


    no problem the bed leveling is top


    however, to launch the second print


    g28;
    M420 S1 (to reactivate bed leveling)


    I lost the offset z and so it's bad because of what I read the G28 that makes a kind of reset


    Do you have an idea to keep the points? for a second impression


    Thank you !!

    That number is my Z-Height - You will set your own Z-Offset
