Frame Adjustment advice

Hello guys, After running a bed mesh, I have this problem: deviation is too high. So which position should I change ? Note that 0,0 is Front Left and the Highest point is Back Left Corner

@C7H fix the x gantry by u scrrwming the rail and then screwing it either left to right or right to left as equally as you can. What is essentiapy happening it that the x gantry/rail is bowing upwards here.

You are using a custom bean on the x. What you can do is: A) diaassbele it and the straighten the rail on a 2020 extrusion with a torque wrench, and the put some books on the custom gantry to make it as flat as possible. Then reasseble. B) be very gentle with this but push slowly down where the Blue areas are. Blue areas mean it is further away so that means that you need to push that area down. Do this gently with hands and then remesh Do it until its more flat Always re home and z tilt after each Otherwise you'll get false results. In your case the gantry is bowing upwards so push it in the middle down a bit with hands Again gently. You dont want to bend down too much.

You are still dipping, add more fiddle with it, and get it as flat as you can. I suggest adding more points so you have a bigger reference to follow on what needs fixing. But when you fix the X gantry, you will see that the frame on the back and sides will straighten as well. So don't touch the y or the bed till you get that sorted out
