-The heatbed for the A8 was increased to 220x220mm from the original Prussa i3 design with 200x200mm. Aparently the power was not not scaled accordingly.

-Some recomendation say you need 0.6 W/cm² for a heat bed. This would mean 290W for the A8 heat bed. But it has not even half(110W) of it.
+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).
 ==== The optimal wire ====
 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.
