Hi all, Just wondering if you had any tips on the heatbed settings in marlin and also heatbed installation. Is there a top and a bottom? Should the small LED be on the top? Are there any settings in Marlin to make it heat faster. My bed seems to only be able to get to around 73 degrees and takes forever to get there. Any ideas greatly appreciated.
