Post MK2B Dual Power Heatbed, Cable, Resistor & LEDs (HC3DPR0030)

This heatbed is designed to be compatible with any 3D printer that can accept the RAMPS MK2B version of heatbed. This heatbed has a dual power capability allowing it to be used with 12V or 24V power supply sources (these are soldered for use as a 12V PCB). It has a central mounting hole on the front side to allow for three point mounting. This is much easier for bed levelling in comparison to 4 point mounting. Additionally, the solder pads have been greatly increased in size, making it much easier and allowing for the use of 1206 surface mount components, which have already been soldered for you. The power cables are also already soldered into place. Please note however, that this does not remove the need to use proper strain relief.
