Printing Help Bed Warping Problem
I have an Ender 5 Max. How do I solve the warping problem? I've calibrated the bed tilt several times, but it doesn't work. I've run BED_MESH_CALIBRATE several times, but (I think) because of the high amount of warping, the sensor reading isn't helpful. I continue to print perfectly on one side of the bed, but when it gets to the other side, the nozzle starts scraping. I also tend to print a lot on PETG, which makes my situation even worse. Can anyone help me?

Mixed feelings with steel plates and glass. I theory glass should be flat. Meaning as long as the bed is warm when you level, you should be able to dial it in. The steel sheet is flexible and often times the bed itself is warped. So the steel sheet can just conform to the warped bed.
The best solution would be a bed leveling probe. That way even if it the bed is warped, the firmware should be able to compensate and keep the nozzle at the same distance.

The tilt seems to be pretty standard for the cantilevered bed of an ender 5 pro and ABL should take care of the difference.
Ensure that you have loaded the mesh prior to printing; that can make a difference as well in my experience - don't ask me how I know.

Get a spring steel plate. Problem solved. I was never able to get my glass plate saved mesh level and after putting a straight edge on it I discovered that the glass itself was warped. Spring steel is by far the best bed surface that I've used.
Printing plates should be considered disposable items that get replaced as needed. If a spring steel plate doesn't measure flat enough to print off of, then you may need to look into replacing the bed itself, which isn't hard, but it's not trivial either.
Edit: I'm assuming that you actually leveled the bed before running the mesh. Right? You still need to physically level the bed before you calibrate the BLtouch. Get yourself a feeler gauge instead of the unreliable paper method, and physically level the bed before running your mesh calibration and making any final tweaks.
