Sorry about your lathe problems, Drew.
I just goes to show how finicky electronics can be. This can happen on anyones product since most of the electronics are made by relatively few manufacturers.
We have a lot of power problems (voltage dips and lightning strike issues) at the paper mill where we have many variable speed drives. Some of the new ABBs are really nice and reliable, but it seems like you get a bad one every once in a while.
The mill is about 120 miles west of the powerhouse that supplies electricity. When a storm moves through, everyone is on pins an needles for about an hour after it is gone.
Needless to say, I keep my VS lathe unplugged when I am not using it.
