Bonsoir,
J'ai essayer de brancher un bl-touch. J'ai surement fait un mauvais raccordement. Je l'ai démonté.
Maintenant, lorsque je fait un auto home, l'axe Y ne bouge plus. L'axe X va à gauche, L'axe Z remonte de 2 ou 3 mm à la place de descendre.
Merci d'avance pour vos réponces.

Good evening,
I try to connect a bl-touch. I probably made a bad connection. I took it apart.
Now, when I make an auto home, the Y axis does not move anymore. The X axis goes to the left, The Z axis goes up 2 or 3 mm instead of going down.
Thank you in advance for your responses.

Hi,if you remove the automatic sensor, you need to update the firmware to the original firmware.

Hi, You can try to see if your probe is demagnetized,
You can try to remagnetize it,
Touch the probe with your finger to see if it can retract properly.
