I have a Fagor 8020 CNC control that will hold a pattern on three axises as long as I run the speed at 60% or lower. Above that the axises move and once all are in the programmed position the control will give a one to two mm signal in the opposite direction and the axises will adjust. The main problem aside from not stopping in the programmed position is that the one to two mm adjustment is happening as the machine ram is in the downward motion of the cut cycle. I have run the machine with the cut cycle off and the axises stil adjust after reching the original programmed position. I can be reached at the above phone number from 7am to 4pm EST Monday through Friday or at the above e-mail.
