Fluid bed mesh levleing reddit

Auto bed leveling should compensate regardless of how far it's uneven. My bed is basically like this just for moving the print head and testing it with a paper. Before each power down, I realign the gantry, heat the bed/probe, and do a height map. Many times the middle will be past 0 so I have to reprobe.

After that you can enable Bed Level to use that mesh as the default. If you do an ABL for any print anyway, this doesn't matter and you might as well disable the bed level as the one created during the print will override the default one for that print.
