Hello

# write fuses
./avrdude -C ./avrdude.conf -c  -p atmega644 -P /dev/ttyACM0 \
    -B 5 -U lfuse:w:0xF7:m -U hfuse:w:0xDC:m -U efuse:w:0xFC:m

Some developers are less than enthusiastic if people neither know how to do things and don't want to follow the written down instructions either. It's obvious you didn't read the wiki page: [reprap.org]

Arduino programs the fuses, but it doesn't hurt to check them with avrdude afterwards.
