About these values
200 W is a typical average including heating cycles and idle moments; it is not the maximum rating on the power supply label. Real consumption varies with settings, material (for example a high bed temperature) and room temperature. For an exact figure, measure it with a plug-in watt meter and enter it in the calculator. When Filanomy estimates print time for unsliced files it uses this printer's speed class (medium, about 2.8 mm³/s effective flow).
