The machine don't have tool change alignement / axis problem, But sadly two times happen the Z axis get a wrong Z position home and going to tool change area unaligned 60mm.
This problem cause a heavy damage to the spindle and the tool change arm due to collision.
When this happen, the home position light of the Z axis is ON, the fanuc screen tell me "Z=0" in machine position and all the I\O ladder signal is OK to allow a Tool change sequence.
This problem is under investigation by Matsuura and Fanuc Tecnician, but i'm tryin to limitate the X axis power only when X axis going to tool change area and then restore after tool change.
P.S. I have some pictures and i try to post.
Thank you.
