Hello everyone! I’m looking for some advice on how to fix my bed tilt. It’s very off and not sure how to even start to fix it. Anyone have any tips?

It’s a pretty common issue. The easiest fix is printing shims / spacers for the left and right Z rods.
And an angled spacer for the back Z rod (depending on how it’s tilted)

Depending on your slicer and GUI, there may be a way without hardware. Also, maybe trying to set up hand moves against the unlevel surface with the lead screw manipulation may help.
If you are using Klipper as the firmware, there is definitely a way (none of which I can recall now) but with manipulation with the leveling tool on the bed and altering the lead screws, you may be able to flatten out the uneven parts to the bed.

I assume the corner at the front is your right front corner?
If that is the case, you should be able to lower your front significally by slipping the forward belt a couple of notches. A notch is something between 0.15 and 0.2mm on that corner, depending on belt tension.
Once you are withing a range of 0.4mm (try to get as low as possible, but the mechanics of the belt only can do so much), there is a number of possibilites. It depends which bed corners are high/low. If the rear corners are even, you can go for option 1. If they aren’t, you have to use option 2 IMHO.
1.) Put spacers on the front spindles. For this the front corners have to be LOWER than the rear. If not, slip another notch on the front belts. In my opinion you should not put spacers on the rear, as thats the reference point.
2.) Put spacers between the frame and the standoffs. DO NOT put spacers between the bed and the standoffs (screws are shorter and the bed is too soft). I used shims from RC cars with 5mmx7mm in 0.1, 0.2 and 0.3mm made from stainless steel. You can use other sizes (e.g. 4x8 would be ideal to have a better fit around the screw and the standoff). That way the bed bends slighty and you should get all four corners even or at least within 0.2mm.
I had to do option 2, beacuse my left rear corner was high by >0.3mm. Can’t fix that with the belts alone. After shimming the other 3 corners to 0.3mm and heating to 70°C (to settle everthing) I was down to 0.08mm.
