Right on the money RCP, that's the downside if there is one. There may be electronically, but I'm not too cluey about it. I'm accomplishing that in a roundabout way by inserting a small roll-pin in the exit end of the ACME shaft simply acting as a mechanical stop as the acme nut contacts it so it can't spit the piston right out at full extension. Raising, it simply will stop at the end of travel.
However, there's plenty of piston in the tube so plenty of warning. With an acme, it won't jamb or bind like a conventional thread I've found so taking it to the stops does not cause it to bind up tight. It'll let go easily when reversed. It's not perfect but they are super strong. A work in progress.
