A little more info would be great. If you are saying that you had pre programed files that are now overbending, I would speculate that in the machine parameters, your ram depth offset somehow changed. Somehow could include a recent power outage or any other instance of rebooting the controller. On my Accurpress controller, there is a data entry point marked "Ram Anticipation" that can be used to correct the errant parameter. You maybe can try re-calibrating the ram, or check the owners manual for the actual offset as recorded by the commishioning mechanic and then comparing it to the current setting.
