Hello, I just purchased a 2009 Precision Mathews 1330 cnc lathe from the original owner. This machine has the Sinumerik 802c controller. Power up, homing and jogging all work fine. When I try to go any further everything is "access denied" . Going to the password page I have entered all the factory passwords to no avail.. The original owner did not modify any of the factory passwords for this. The Siemens online tech gave me the additional password of ECHTZEIT, but this did not work either. The machine had sat unused for 5 years previously to my purchase. Can anyone help? Thanks!
