Bonjour tout le monde

J'ai un petit souci pour la config de l'autoleving, j'ai suivi la procedure indique sur le site [thebreizmaker.wordpress.com],
Quand je lance le fichier a imprime, le palpage ce fait correctement puis o moment d'imprime je me retrouve avec la buse en l'air qui commence
a imprime alors qu'elle n'est pas sur le lit,
dans config, j'ai mesure la distance en Z entre le palpage et la buse qui est de 5.64mm
meme en modifiant la valeur #define Z_PROBE_OFFSET_FROM_EXTRUDER cela ne change rien!

J'ai le niveau du bed qui est trop haut et j'arrive pas a le descendre

J'e m'etais retrouvé dans la meme situation. Essayes de faire le reglage via le LCD

comment je procede ????

probleme résolu, j'ai réglé via l’écran offset Z
