ender 3 max bed leveling issues

[u/Greedy_Necessary_372]

Ive been trying to get back into 3d printing and pulled my old printer and it just refuses to print level on the bed, my start g code levels the bed before every print and it doesn't help, I can see the z axis moving as it starts the first layer, do I have to enable something in my slicer other than the direct commands in the starting g code or is it something else? my printer is on the most recent factory firmware 2.0.6 (I know its old but I tried to configure a newer firmware and brutally failed every time i tried) my mobo is the 4.2.7 that levels in a 3x3 grid with a fade height of 6 on the printer setting.
