I have had this problem since I bought this machine but now it just wont home. The Xaxis keeps giving me a x+ over travel. All proximity switches are working and the hard stops. P+CAN results in the machine hitting the hard stop. I have had the grid shift from 0-15000 (used to be 6699). It has a 21T control on it, and absolute servos. Do i need to reset the home position?
