is there something wrong I'm doing because i didn't disturb the setting. i don't know what happened.

i want the cnc to move back until limit switch is no longer triggered. me  guide me??

Hi,
you are confusing limit and home switching.

When Mach is in 'Homing' mode it will travel until the home switch activates and then backup until it deactivates.
When it is not in Homing mode then the switch is treated as a limit and Mach Estops immediately, no if's,
no but's, it just stops....and that is what its supposed to do.

I have always recommended having separate home and limits switches, so that would be six limit switches, two for
each axis, and three home switches, for a total of nine switches. Most people think that's too much bother....but then you
have this issue. You decide.

oke got it. but ive been trying,its only setting home switching. how do i set up limits only so it can move back. ive tried youtube but all the videos are irrelevent. if you could show any SS from where i can see.thankyou 

Hi,

how do i set up limits only so it can move back.

If Mach detects a limit event, ie one of the limit switches it Estops....it DOES NOT MOVE BACK, in fact the only way to get it to move AT ALL is to
manually use 'Limit Override' and jog it off the limit switch.
