I am running DHC plasma cam software with hypertherm cutter. Still learning the software, but with this flange, seems I need more training. hehe
Basically what I have is a 4.5" diameter circle, with x,y being dead center, then from there 5 holes on the outside.
I can draw the 4/5" circle, and find center then draw the 60.1mm hole, what I am having trouble is the holes on the outsides cordinates.
I am just looking for a pierce point for the outside holes, then I will manually drill out the holes on the press.
