Hi , Im new to CNC, i just bought a 1986 hitachi seiki ht20 lathe with a fanuc 10tf controller, I have overtravelled with the z axis and i reset the clutch, but i dont think its right because the red light near the clutch is on and i get ps 200 alarm message, and when i zero return the numbers read 300.00mm plus and it doesnt return, the x axis is fine. could i have turned the screw too much, how do i re zero the machine? Im also looking for good cnc programming books, im located in perth Western australia,
Thankyou,
Michael.
