Here is a video to help you manually level a bed. Using a paper method, you can manually level your bed with precision! Just follow along with this video, and you can achieve a perfect first layer! Check it out!
Okay I don’t know what I’m doing wrong here. I am using this method and am using the gcode generated from his site to test the first layers. I use a piece of paper and level everything and then do the measuing step and all seems ok… but my prints are coming out as if the nozzle was way above the bed. I must be missing something simple but damned if I know what it is.
