Thanks. Can't say it was anything you posted. Running the latest version of everything. Everything was fine the day I shut it down after cutting a file. Shut down control software, shut down computer, shut down control box. Same way I always do it. Only thing about anything that was different than normal is I had plugged a space heater into the same surge protector outlet the machine was plugged into for a few hours, but the machine was OFF the entire time the heater was plugged in. I unplugged the heater before I turned the machine on. I normally try to keep everything else on a seperate circuit, but being it was freezing I needed an extra heater to warm things up before I could work.
