BLTouch Duex5



  • Bonsoir après avoir passer toute la journée a essayer de faire fonctionner mon BLTouch https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/#configuring en suivant se lien sans succès je demande votre aide.
    Lorsque j'allume ma machine mon BLTouch se déploie correctement en fessant les Macro test (M280 P7 S120) marche aussi mais en demandant un HOME Z la le deplacement se fait correctement mais la pine se déploie pas.

    Post your config.g and homeall.g

    The homeall,g must contain a G30 to call the probe.
    The deployprobe.g and retractprobe.g macros must contain the corresponding M280 servo command. Test with M401 and M402 to deploy and retract.

  • M401 and M402 it’s working normaly



  • I think my Homez.g file is not good either



  • @chris974M
    as Phaedrux said, zou are missing a G30 in your home script.

    i would suggest that you use you config.json to reupload you config to the configurator and enable bltouch there. it will generate all thins correctly for you.



  • Ok si je fait sa est ce que je perd mes autre confît.g ( XYZ dual axis ) ?


  • Moderator

    You can just compare what is different and take just the zprobe section and copy and paste it into your config.



  • ok i try



  • C'est ok merci
