Do you have a parameter backup? If you don’t you’ll need to reach out to the machine builder and see if they have one on file. To get everything running you’ll need your CNC parameters and diags at least. Check the electrical cabinet, in my experience there is typically a folder/binder with a factory printer parameter sheet that should get you up and running. If you have a digital copy of your parameters, you can edit your IO parameters and input them via RS232
