Et maintenant, problème de limites

Bonsoir,

J'ai pas réussi à trouver comment passer mon premier topic en "résolu", mais par contre la CNC fonctionne (grâce à Amédé en grande partie).

Et comme le dit mon nouveau titre, j'ai un pb de limites. En essayant de prendre depuis le début :
- limites câblées pour l'axe X, en espérant que ce soit sans erreur, sur "normally close" (photo 1 et 2 pour la BoB, le rouge avec le marron et le noir avec le bleu pour pouvoir les passer dans les connecteurs verts de la carte)
- le pin 10 du port // est sur "toutes les limites X"
- le résultat est "jointure 0 en erreur sur un contact de limite " (photo 3).

Il me semble que ce n'est pas très original mais je trouve pas la solution tout seul. Pour compléter je joins mes fichiers conf et hal, au cas ou.
J'ai lu quelques trucs sur le sujet, mais ça me paraît compliqué et surtout, pour commencer

je ne sais pas si mes limites fonctionnent.

Ma première question serait donc : comment les tester ?
Merci d'avance et bonne soirée.

google translate says:

Good evening,

I have not managed to find how to spend my first topic in "solved", but against the CNC operates (through Amédé mostly).

And as my new title, I have a problem limits. Trying to take along:
- Cable limits for the X axis, hoping that it is without error, on "normally closed" (picture 1 and 2 for BoB, red with brown and black with blue to pass them in the green connectors from the menu)
- Pine 10 // port is "every X limits"
- The result is "0 join in error on a contact boundary" (photo 3).

I think it's not very original, but I can not find the solution itself. To complete my next conf files and hal, just in case.
I read some stuff about it, but it sounds complicated, and especially me, to start

I do not know my limits work.

My first question would be: how to test?
Thank you in advance and good evening.

Normally closed limits are the correct way to wire them. If you made a configuration with the Stepconf Wizard invert the inputs.

And more google translate:

Normalement, les limites sont fermées la bonne façon de les câbler . Si vous avez effectué une configuration avec l'Assistant Stepconf inverser les entrées .

Are you getting this error during homing? If not then electrical noise can be the problem. Describe your machine a bit that may help.

I only have errors when limits switches are connected to BoB, and the machine works well when limits are disconnected.
As I have 0V (zero volts) when trying to work, I have 4.7V when actioning limits with my fingers.

I prefer to post 2 photos of the machine, cos my english isn't good enough to describe it, sorry :unsure:
The table is X = 900mm (36"), Y = 550mm (22") and Z = 160mm (3,5")





Thanks for interest and have a good evening if on the other side of atlantic.
