"Can't issue MDI command when not homed" even when homed was created by xaerdna
I am running a High-Z 720 CNC with Zero 3 controller and LinuxCNC. It has been running fine for close to a year. Now I cannot issue any MDI commands, and I receive the error "Can't issue MDI command when not homed". The machine has been homed, and the "homing-symbols" next to each axis are set.
Running the machine in manual mode works fine. No configurations have been changed since the system was setup a year ago.
I have not been able to find any discussions on similar issues. Does anyone know what this is about?

Figured it out. Needed to add "HOME_SEARCH_VEL = 0.0" and "HOME_SEQUENCE = 3" to the third axis in ini-file. This will set the third axis' home position to the current position, which is required as it has no limit switch. For some reason, LinuxCNC did not complain about this before..

The other option in NO_FORCE_HOMING in the INI file.
linuxcnc.org/docs/2.7/html/config/ini-config.html#_traj_section
But you should probably consider fitting home and limit switches
