I’m not even sure where to start. Basically, my bed is sloping out heavily to the corners specifically front right and back left, measurements from Octoprint as below:

Having already made sure everything is tightened up and square, and even getting a spirit level out on all axis, I’m not even really sure where to start with getting this level. Any help would be hugely appreciated!
All sorted now, swapped the outer support posts for silicone, kept the inner ones stock, and now the bed looks like this:

There is what appears to be a bit of a ridge down the centre, but try as I might I can’t seem to adjust for it without throwing out something else. Bed level test print is all but perfect anyway, so I’m happy now, and on with the printing!
right on,
get an indicator mounted to the extruder and cold tram the magnetic surface. you can squeeze the biscuits back an forth til its close before running g29
close enough is the goal IE < 1/4rth your initial layerheight total deviation over the bed.
yay say 3~4 thou TIR
remember if its out solely on the X axis, turn one z coupler a 1/8th turn while the power is off
it holds that adjustment…
