V3.1 400 enclosed bed mesh
Hey everyone hope your all doing well!
I am working on my V3.1 400 enclosed printer.
I am having a heck of a time with my first layer and my bed mesh since replacing the left and right X axis joiners due to my first set cracking.
The first mesh looks as if the back two corners are very low and the back center is higher leading me to think something is bowed however the front of the bed looks relatively flat. SEE MESH 1
Thinking that the gantry rail was bowed I loosened and re set the rail and also adjusted the front corner of the frame based off the frame squaring video. SEE MESH 2
The last mesh is after I heat soaked the printer. SEE MESH 3. Its really bowed now. Any help is greatly appreciated.

Keep in mind its a 400 and its enclosed, so the bow itself could be the bi-metalic x gantry, if its sitting on an aluminum extrusion.
MESH 2 still has issues, as you can see you have a dip in the back right, which means, you need to raise the the right front part, of lower the left front part. I'd fix that first.
Then go back to the x gantry,
Aluminum and the steel rail have different thermal expansion, so this can lead to the x bow.
You can midigate it in various ways, one of it is to try the Dual Rail setup.
Thank you for your input I'll try this and report back.
