questions about limits of the axes

Sorry for the previous question.

I have a doubt.

when my machine reaches a limit switch, alarm linuxcnc obviously. But the only way to remove the alarm, manually moving the axis, because if this does not start linuxcnc, if this lobbied the limit switch

my machine have hidden the screws, so you can not move manually

there any way to prevent this from happening? or I not doing the process correctly.

not there an button "O.T release"?

thanks

If I understand your question properly, all you need to do is click on the 'Override Limits' tick box, press F2 and jog off the limit switch.
(assuming you are using Axis)

As ArcEye mentioned, the override limit button on the Axis screen should allow
you to jog off the limit switch. But, if your limit switches force the system to
E-stop or disable the servo amps, then you have to have a way to override that
condition.

Secondly, you should never hit the limit switches. Once homed, the software
limits are active, and when properly set, you cannot reach the limit. if you
try to jog past the soft limits, the machine just stops at the soft limit. if you
program a move that will exceed the soft limit, you will get a message when
you hit "Run" that the program exceeds the + or - limit for axis "n" at line
1234 in the program. The Axis 3D preview shows a wireframe box for the
machine limits, and another wireframe box for the limits of the program, so
the excess travel will be quite obvious.

For all this to work, you need to have homing set up, and you need to set
the MAX_LIMIT and MIN_LIMIT values in each [AXIS_n] section of
your .ini file.

Once you have done this, it will save you hours of frustration! Nothing like
spending many minutes aligning a piece of stock on the table and then
finding out you put it in the wrong place and the machine can't reach the
entire piece.
