Ha ha ha! That's some pretty good stress testing!

Good to hear that I wouldn't have caused the damage. In my initial test when I was setting current etc. for the first time I remember the marked performance increase when going to the higher current so clearly it's been like this since day 1.

One other very quick question, I have a job next week which I want to use this on. It won't be very taxing, slow moves, nothing crazy, and it still works fine just makes noise at that speed. Do you guys think it's still ok to use this? I'm not going to cause further damage? Hard to say I know.
