 Some recommendations say you need 0.6 W/cm² for a heat-bed. This should mean 290W for the A8 heat-bed, but the A8 is not even half that value (it's only 110W). Some recommendations say you need 0.6 W/cm² for a heat-bed.

-The original wires from the Anet printer are thin and therefore ​have an resistance ​which lead to an power reduction ​of the heat bed. If you use extremly ​thick wires you it will be a mechanical ​issue for the Y-axis stepper and as cables are made of very good thermal ​conductors it will remove heat from your heatbed by conduction. This rough estimation shows that AWG 9 would be an Optimum from the thermal point but the difference from an AWG 14 is minimal and AWG14 is conciderable ​more flexible and can be crimped with blue pre insulated crimps. Also the 1 W more for AWG16 would be ok as this as 1W would increase the max heat bed temperature by only 0.5K. +The original wires from the A8 printer are thintherefore ​their resistance ​leads to an power reduction ​to the heat-bed.
