Hi all, thanks for your support. We bought this machine used. The first owner was in the auto industry and he has a maintenance plan which sounds like run to fail. Then the machine was sold to another company, installed it but never went into service. They bought a new machine and gave the Twin in exchange to the reseller. Then, the machine reseller sold us this Twin 42. Our machine is a 2004 with the 840D control. We checked with Step7, but the program is so huge, we were not able to find anything. We have some experience with Siemens programs in industrial application but we don't have any experience in the CNC part. So we don't really know where to look at. By looking deeper in the backup of the machine, at some point, the external absolute encoder of the B axis was replaced by an incremental. So we tried older backup and we have some error like ; wrong encoder type, switchover impossible etc... It's only a couple of days ago we noticed that it may come from the X1 axis. DB39.DBX2.1 = 0 DB39.DBX21.7 = 1 In .zip, you will find all the screenshot of the "service drive", "service axis", the locks and more info. Do you see anything obvious ?

Can you check db39.dbx61.4 (axis stationary)? |
