Hi All.
I've got a Z-Axis motor overheat code on a cold machine that i just turned on this morning. temps in the shop get pretty low during the winter at night and on weekends when we're shut down (40-50F) We warm the shop up before turning on the machines though to at least 50-60F. This morning i got this error coade along with a Z MIR message and gibberish on the screen. Any ideas on where to start the hunt for the problem? I'm attaching a pic of the screen shot for reference. Also I noticed when i switched screens to the memory screen it showed almost no programs almost like the CPU is gliching or something. ...
