hmmm,
I think I am getting some noise for sure. I have been getting a number of unexplained E stops lately, as well. Dont really know how to account for it though.
I will also say this. My house was struck by lightning a few weeks ago as well, which fried another controller I had in my shop (left the computer on, but not the controller and fried a Bob Board), but not this one. Luckily this one was off and seemed to be OK. I dont know what kind of a current spike or damage could occur when the power supply was off and the computer turned off as well, but I suppose its entirely possible that did something to it. Again, wouldnt know what to test to be sure without just replacing each component and seeing if that fixes the problem. That seems like an expensive way to check things though.
