LinuxCNC is 3.4.9.
I am using the gmoccapy interface with EtherCAT bus-controlled drives equipped with absolute encoders. The values HOME_OFFSET = 0 and HOME = 0 are set in my INI file. The zero point has already been configured on the drive, yet every time I boot LinuxCNC, the Xg54 position reading increases by 256 compared to the previous session.  why?
