We've got a '97 3016 with a CNC88HS. We bought the machine new. Recently it began acting strange during tool changes. It happens when you call a tool change,either in Auto or MDI, and you are beyond Y-5.0" in the machine coordinate system(cold start). The head retracts to tool change height and the machine moves to Y-5.0, changes the tool and then returns to the previous position. It does this regardless of fixture offsets. It refuses to change a tool within 3" of the end of the Y axis travel. It even does this using the tool setting utility. The positive side of the Y axis is not affected. So far it has not caused any problems, just some unprogrammed moves while running programs. Has anyone seen this before?![]()
