I was on pins and needles here, hoping you'd get the cup underneath on time! I'm building an AR-4 now (as of 3d ago). Please tell us more about your AutomationDirect PLC, which one, etc.
can it pick up a steel bar about 1.5 lbs and press it against something (vertical) with enough force to buck a rivet? how many lbs of force can it apply in such a situation?
