        Right there it says that it can/will overshoot the target temp when calibrating....by how much depends on how powerful the heater cartridge is. Something to watch out for that I have seen all too often is to make sure you have the correct voltage heater for your hotend. Many people will order a hotend or heater cartridge that is rated for 12 volts yet have a 24 volt power supply...this will make it heat up crazy fast and be pretty much uncontrollable and unsafe.
