Hi I have just updated the firmware on my I3 Mk2s and every time I try to print I get this error:

>> MMU not responding - DISABLED
>> // action:pause
>> Extruder fan speed is lower then expected

Any ideas?
Thanks

Since the mk2s does not measure fan speed you most likely installed a mk3 firmware.
