Hello All, I have a program that I have used several times and it worked fine. Part of it is drilling holes, I tried again today, when it gets to where its supposed to drill several holes, it moves along the correct tool path, as it gets to each hole it very briefly stops, hums, doesn't drill hole and moves on. I did mess with the "config. > control > motor and thought I got it back to the original numbers, but it still does the same thing. any suggestions?
