  • I have to include a G29 line to my gcode in order to avoid touching the bed each time with too much effort (close to break something).
    But the file I created can't be save in 'gcode' mode, but just in docx.
    How can I have this G29 added while keeping the gcode operationnal for my printer.
    Many thanks,
    Dominique

    If you continue with the manual solution, alter and save the file via notepad or notepad++ instead of word, then save it over the original file.

     

    Alternatively, you could also probably add a G29 either in a post-processing script (accessible from the plugins top bar menu in Cura), or even in the start gcode, in machine-settings (accessible via the printer/preferences).

    Many thanks for your answer; I'm now understanding how to do, as you made it clear to me.

    Good evening,

    CFFFP_Bouchon de banc de tour G29.gcode

     

    Sorry to come back with it; here I attached the Cura gcode which is causing me the trouble of 'strong touch' of the bed in all the cases.

    Just I added the G29 code earlier to check bed level before printing but this still not workable as the noze is forced in bed and I have to stop it in emergency.

    Could you check the first lines in order to check my own.

    Many thanks,

    Dominique

    You should do a G28 1st, then do G29 

    If you want a 3 x 3 grid try G29 P3

    Hi @Domi1958

    I think what @obewan saw was this from your gcode file.

    M82 ;absolute extrusion mode
    G29 ; auto-level
    G28 ;Home
    G1 Z15.0 F6000

    You need to switch the G29 so it is below the G28.

    In Cura select "Settings / Printer / Manage Printer" and in the next dialog select "Machine Settings".

    On the left is the StartUp Gcode box.  You can edit the code in the box so it's like this:

    G28 ; Home
    G29 ; auto-level

    That way the printer will know where the nozzle is before it attempts to level.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
