Hi, I`m new and i was bought first EDM machine. Machine work fine (on hand control) several days and everything looked fine. When I was trying run first program machine work ~ 30 secounds and stopped without error on Z=0 point. Then sensor "Touch" all the time is "ON" and I can`t run any programs and can`t use hand control to move axis. I checked the voltage between the table and the spindle and looks fine. HELP!
