I have not used the liquid autosampler for some time, but now I have an issue. After restart, the light changes from green to yellow, and I immediately get two error messages: Plunger motor 1 is not homed and NdlGd motor is not homed. I tried to park the tool, but I get the same message. I do not see any obstacles. I also tried to perform a home drive, but the same message appears. I have, of course, restarted the autosampler several times. I am not sure what the next possible step should be.

The plunger message is no longer there, only the motor. When I go to robotarmleft and press NdlGd motor 1, it moves but gives the error M9024: homing of NdlGd motor failed.
