excessive power is applied during the disassembly/assembly of the Extruder module.
* If printing is done while the Extruder module is not accurately mounted to the printer, the
module fixing bolts are not fastened, or the Extruder cable is incorrectly connected, it may fail
to print or cause a breakdown. Use the printer after accurately mounting it.
* Since the Extruder module contains an electronic device, be cautious not to touch with a wet
hand and be careful not to get an electric shock.
