Sure enough, yesterday I brag all machines in my area are running. Today, the speed control for the ID grinder wheel head went south. Managed to manually bypass a relay, hit a few reset and change around some parameters in the controller to limp through until we can get a new unit in. I swear the machines can hear and understand. They seem to work best when you cuss at them. Set me back a few hours, but it is semi-functional. Eleven hours, and I am out of there. Hopefully tomorrow will be a bit smoother running.
