Delta printer from scratch issues

[User_8232]

Hi everyone.
I need some help regarding the homing of a 3d delta printer, and it’s my first attempt to create a 3d printer by scrap.
My problem is regarding the homing, when I do the homing 2 out of 3 endstop work properly but 1(always one) doesn’t work properly(see video).
While the support is hitting the endstop, it moves a little back like the others, but then move up again and doesn’t stop 'til I do it manually.
there is someone that have some idea to solve the issue? Hope everything is clear enough, otherwise ask me
Thank you in advance.

It sounds like the third endstop isn’t registering correctly, there may be a short, or loose connection.

Hi, thank you for the replay.
How can I check for your suggestion?
And u think it’s a problem regarding the hardware or software?

It look like software problem. The idea is carriages move home quickly then move down to un-triggered the endstops then home at slower speed to eliminate sensor/line delay.
I look like that one did not move down enough. Try look into the firmware setup, homing section to increase it a bit more.
