origin issue problem was created by Retiere
Hello, I chose Hall effect sensor for homing.
These are closed in normal position and open as it approaches the magnet.
Except that on linux he takes the pick of moose when he receives power, I would like to know if we can reverse this option. that is to say the original take when the current does not pass.

Invert the input pin. Most inputs have an in-not pin.

Must be a hardware issue. Not enough information.

You have to be more specific in your description, it not work does not tell what is going on.

yes you have reasons. I will try to be more precise.

I would like to change the configuration of the EMC2 tunes. Because my sensor cuts off the current when they are switched on. And EMC2 detects a limit when the current goes on I would like to know if there is an option to reverse this.

Is this more understandable?

As JT explained, if the limit/home switch polarity is wrong you need to chose the 'not' input
option on the input that is driven by the limit/home switch.
Note that you may still have errors but you must get the input polarity correct to proceed.

You can use the "watch" option in axis to check the limit/home switch polarity

Yes but it would be helpful if you would post your current hal and ini files so that specific recommendations can be made for your hardware
