OK, the move exceeds limit mans the machine is not properly set up. Do you have home switches?
If not, you really should set up one of the methods of homing the machine to limit switches.
Once you have the machine homing to a repeatable position, then move the machine to
the limits of mechanical travel and observe the coordinates in the machine coordinate system
(G53 or I think pressing the @ will display that coord system.) You will apparently have to
expand the limits in the .ini file where you have MIN_LIMIT and MAX_LIMIT in the axis
that is hitting the limit (Z is the first one, but you may have others when you clear this one
up.) Once you know the limits of travel, then use these values in the .ini file for
MIN_LIMIT and MAX_LIMIT. Then, as long as your workpiece and program fit in
these limits, you should not get these messages anymore. The great thing about
setting all this up is that when you load a part, touch off and then load the program,
you will get a message if the program would exceed the limits before you even hit run!
You then can reposition the part before starting so there will be no problem.
