On jog away, after you paused program with cycle stop, red button, pressed axis you want to move, lets say, Z, than hand jog than moved on that axis, then pressed memory and cycle start, green button, and the mill should return to its previous position and resume program, sometimes it doesnt.

it happened to me on all three axes.

it goes about 1mm more in that axis, lets say Z axis, it returns 1mm lower than makes the move, just freezes after it goes to the end of that cmd line and continues spinning but does not feed (move on any axis).
On the screen you can press anything but it won't react, except for RESET button.

what could be the problem?
it doesnt happen that often but it does happen.
in last week 2 times.
