Bed mesh not working correctly
Hi. I've been testing my V Core with some small prints and seems it's doing some strange things. My bed mesh heightmap looks like a V, but inspecting my heating bed seems to be flat. This is being reflected in the prints as you can see on the second picture. Seems that the hotend is too close to the bed, but I don't know exactly what should I check here to try to have a flat bed.

Looks like a bump on the gantry. You inspected your bed now inspect your gantry extrusion and rail, it got bow that rises the toolhead up in that spot.
I'll check first thing tomorrow morning the gantry and probably will remove the entire rail to further inspect it. For now I was able to check the hotend carriage in case it was not tight enough but it doesn't seem to be the issue, as I still have that same weird mesh.

We are talking about Y extrusions and rails here just to be clear according to the mesh.
Yes, but I'm checking the whole XY mechanism because I first had an issue with the X rail not being 100% parallel to the frame as I did not tight the belts correctly and it was not mounted correctly, so there was a bit of a gap
