Insulating the bottom of the board, and possibly covering the unused sections of the top surface can help these boards heat up faster and hold temperature better, especially in the presence of a cooling fan. We've found that the lower wattage beds struggle to hold the higher temperatures. On all of these beds, we like to use a heat spreader like a thin sheet of aluminum between the hotbed and the printing surface. If you have a less capable power supply, pick a heat bed that is well within its power specs. If you have enough power, we would suggest the lower ohm heat beds, as they will heat up more quickly. Usually this is because the heat bed is using more power than the power supply can reliably provide. We have heard of some customers having trouble with their printer when the heatbed turns on. Instructions are clearly marked on each board. For 12 volt systems, you will run the heating elements in parallel, while 24v dc systems will be wired in series. There are two heating circuits on each board. These MK2 Hotbeds can be used for both 12 and 24 volt systems. We have measured and sorted these MK2 hotbeds by their room temperature resistance which gives us a general idea of the wattage of each. We provide you a special option not normally found, a chance to pick the resistance (power level) you desire for your printer.
