Trying to reload the system tapes on the above machines due to memory loss after a long storage period.
Problems encountered are thus:
1. Sometimes the tapereader reads the tapes but stops after a few seconds sometimes longer. I have even managed to read a complete tape, but of course the same problem came up when loading reel two. I suspect a tapereader error!?
2. Got the tapes on disk in ASCII format trying to load them this way. Can`t get the PC to communicate with the CNC. I will check out the RS232 with a break out box tester. Never used one before, what do I look for? Got various suggestions for DNC setup, does anybody know something that works, including cabling?
3. When starting up the machine I get a one-line message "memory lost.... ". Doing the firmware diagnostics and tapeloading (as described above) works when this message is on, but sometimes the screen is full of letters in a caotic and random and nothing works. Any suggestions what this may be and how the get the machine "back to normal"?
Comment to all above: Quite sure that the boards and other hardware are OK, the diagnostics reports no error. Got two machines so I can interchange parts if I suspect any faulty parts.
Any suggestions received with thanks
John
