My plasmaCAM will run but keeps popping up with a notice saying "Communication Error Code 128". I cannot find any purpose for this and have done everything I know to do. The machine has done this before but I have been able to work around it or the problem just quit. Do you know of anything that I can do?:drowning:

I don't know that code, but..
You are using a 6' parallel port cable?
Not using a laptop to run the machine?
