HELP difficulty setting end of travel and return home

Hello,
I am new to your site as well as a new practitioner of cnc machine. I am finishing my machine and arrive at the most delicate part for me, the purely programming or electronic part. the system is an uc300eth coupled to UCBB and uccnc as support.
My issue is the following,
1 / I placed limit switches (NC) on each axis, these are identified in diagnostics, let's take the X axis, if the latter moves laterally and reaches the limit switch, it is impossible to move the carriage in the other way, a window pops up and tells me

"the software reset logic is active. clear the reset condition by pressing the flashing reset button on the screen. if the reset condition cannot be removed, it may be due to an external electronic stop button being pressed or a limit switch on the machine tool please check the diagnostic page for the condition of the input signals "".

which method should be applied?

2 / I also installed home limit switches (NC), also on the diagnostic page ok, but they do not interrupt the movement when I click on the corresponding icon, Why?

I think it's simple for professionals but for amateurs, there is nothing simple, believe me.

Thanking you for the help you can give me

Item 1

Press the " override limits " button as shown below, then press "reset" and then jog the axis back off the axis (using the arrows on the keyboard or the jogscreen + PGUP/PGDN for the Z axis)

I have to think about item 2

k



Which ICON? On which screen??

The LED's on the diagnostics screen are LED's not BUTTON objects.

they just show indication of status.

Hello, for the icon relating to the return home, the x-axis, small red icon. is this icon not supposed to bring the cart to its original home position?

for what is diagnostic, x0 y0 and z0 in port 1, which gives me x y z home. my setting is it correct.

Can you upload your profile, or at least post screenshots of the axis setup screens.

Hello, is there anyone who can assist me,
I don't understand why the limit switches have no action if I run a home all operation while my limit switches are working

I suspect your home switches are set wrong and should be active high not active low

as the diagnostic screen shows the home iOS are active

hello and thank you for your answer
actually I found the active low position but these are the same limit switches (NC) as a result I positioned them like the others. but in the diagnosis they appear active. when I switch to active hight there is no effect in the diagnostic
What is
G28.1 Z
then
G28.1 X
then
G28.1 Y
