Store memory does not work!

Hello,first I changed (settings) the nozzle temperature,and the fan speed !Then I scrolled down and stored it to the memory !
Then I restarted the printer and loaded the memory,but there are no temperature or fan speed stored !
I tried it more than one time,and with different sizes,but store in the memory is not possible !
Does the EEprom not work properly ?

Sorry about my bad english !

Thanks,Georg

You should change these settings in the slicer configuration or in the Gcode.

Thank you verry much for your answer !

I asked, because “Velleman” wrote these procedure in the description
from the “LCD” !

Regards,Georg

Those instruction are for updating the firmware.

is it possible that you changed them in the job settings instead of the device settings itself?
