It can be seen with these curves that a quite thick insulation is nescessary for a large effect onto the heat curve. | It can be seen with these curves that quite thick insulation is necessary for a large effect on the heat curve. |

Nearly half of the of the heat is lost by infrared heat radiation. Therefore an aluminum foil at the bottom is more effective than 6mm of kork. To reduce the heatloss even more combine them. | Nearly half of the of the heat is lost by infrared radiation. Therefore aluminum foil on the bottom is more effective than 6mm of cork.

It can be seen with these curves that increasing the voltage on the heatbed increases the speed and max temperature. This can be achived by 3 measures: | It can be seen with these curves that increasing the voltage on the heat-bed increases the speed and max temperature. This can be achieved by 3 measures: |
* Use thicker wires between HB and board and board and power suplly.(see the optimization chapter below) | * Use thicker wires between heat-bed and the board, and board and power supply (see the optimization chapter below). |
* Solder the wires directly onto the heatbed (some soldering practice needed) | * Solder wires directly onto the heat-bed (some soldering practice is needed). |
* increse the voltage of the power suplly. This might be risky and is only recomended if you have [[reprap:anet:a8:replace_connectors|replaced the orignal connectors]]. The power suplly might exeed its limits, therefore a power suplly with 30A at least is recomended by some users if 14V is used. Thoretically the arduino in the Anet board can go up to 18V but only 12V is recomended for arduinos. So it should be possible but it is your own risk. | * Increase the voltage of the power supply.
