RepRap 3D Printer dual power PCB Heatbed MK2B Heat Bed Hot Plated 12V 24A Descriptions: FeaturesBrand new and high qualityDimensions (Outer): 214mm x 214mmDimensions (Heat Bed): 200mm x 200mmLaminate FR4 1.6±0.15mm2 Layer, 35µm CopperPower Input: 12V/24V DCCopper Plated HolesCome with resistor and LEDs soldered,basic soldering skills needed to solder the power wireThis 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. It features 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. First level the side with two holes and fix in place, then level the side with one hole. A glass plate is highly recommended to provide a truly flat surface and rigidity.Additionally, the solder pads have been greatly increased in size,making it much easier and allowing for the use of 1206 surface mount components.But this does not remove the need to use proper strain relief.Please note: ABS filament is not recommended.
