I was using the PCNCII this afternoon, and as I was moving around Mach3 screens, the mouse stopped responding for about 10 seconds. It happened a couple of times. At first, I thought it was my trackball type mouse, but what happened next makes me certain it is not. I picked up the jog controller, and moved the Z axis. I switched to the Y axis, and used the "spring" wheel part to move the table. I let go of the spring wheel, it returned to center, but the table kept moving! I freaked, and hit the EStop button. (It was major panic, as I haven't fixed the Y axis limit switch actuator yet, so it would have slammed the column)
My first thought was "time for a cold boot". I exited Mach3, and selected "Shut Down". It hung when trying to shut down. I turned the power strip off, waited a minute or so, and turned it back on. At this point, my memory gets a little fuzzy. I don't remember exactly how many times I booted and shut down. I am positive I had it hang a couple times while booting up, once at the "Intel" screen, and once at the black "Tormach" screen. It hung on a few shut downs too.
Grasping at straws, I stopped turning the power strip off and on, and used the push-button on the computer to boot. I think this might have helped the situation. Once I had a good boot, I ran the DriverTest program. It indicated about 23,600, and half of the bar indicator was green. There was an occasional small spike on the graph.
Following that, I used the mill for 3 hours without a hiccup. Lots of mousing, switching between screens, jog controller, in and out of wizards, and cutting in the air. After I was certain my G-code was good, I even made some chips.
So, has anyone else had something like this happen?
