I've had my machine for over a year it's a 4800 with an 80 amp plasma. Use it everyday I love it. There are a few options that I can't seem to figure out. One in particular is nesting. I played with it for quite a while but still can't get it to be as efficient as myself nesting at the computer manually. How about a video that actually walks you through Nesting in detail. I have attended two schools at your factory location and we did blow through nesting one day but I cannot seem to recreate.
