I have an old Colchester CNC 500 which developed a memory fault and lost ALL parameters. I have a backup of the User parameters but not the important Options and Diagnostic parameters which are normally listed in the NC documents in the rear cabinet.
I 'd be grateful if anyone with the same machine would share their settings, otherwise I think its very dead.
I hope someone can help you out.
If not, I think for that series there are only 6 bytes of options (2 groups). Wouldn't take long to go through and find the few you may need if any.
A few hours of time for the machine will be cheaper than a re-control or new machine.
