Hi, I have a new 3-axis mill machine with a Siemens 828d controller. I am encountering a problem in tool change. As I call tool change through Siemens tool management screen, z axis returns to home position for tool change but this home position is 10 mm out. Due to this problem, as the arm rotates for tool unloading on spindle, it gets stucked and Magazine motor overload alarm is generated. Kindly can anyone tell me how to adjust Z axis home position for tool change? One more thing, ref. position for tool change is a different from machine ref. point
