Its disturbing to me also. When I press the jog button (arrow key) the machine travels in the correct direction but just doesnt stop when the button is released and no other buttons on the keyboard have any effect until I use the mouse to click the stop button on screen. It also disables all the external inputs , estop etc. Once I click stop on screen the external inputs seem to work fine as do the other keyboard functions, s= spindle etc.
Considering the wieght of my crosslide and tool changer and the speeds this machine will travel its down right scary not having an estop.
What has me confused is this machine has run fine for ages, and not s single thing has changed, been using the blue lathe screen set since the begining. I do notice that all the z offsets for every tool in the library have changed to odd random numbers also . I will load my XML in a few minutes . Thanks
