Hello,
I got a used Cortini M500 3years ago.Machine was out of operation and I repaired the spindle drive,Y axis ball screw bearing,lubrication tubes of X axis,flattened the work table and many other problems on the machine.
The problem of loosing PLC program started from the first startup of the machine,most days starting the machine in mornings when it was shutt down last day afternoon the PLC program was OK,but if we started less than 2or 3 hours after shutt down the PLC program was lost.
Its about 2 months that we loose PLC program every day.
I think there is a hardware failure in the CPU board,I have discussed this to a technition ,the CPU board must be cheked.I am looking for a suitable time to do this.
It took me about 2 month to solve the DNC problems of the machine.I have to study my records and will explain it to you in details.
