Bed bowed along Y axis
I followed the general advice to adjust the gantry and achieved a consistent level at the corners of the bed mesh. However, the Y axis looks very bowed. I have not yet put the PEI sheet onto the bed, so the meshes seen are of just the bare metal bed. Heat pad is not installed.
* I tried loosening the Y axis rails and re-tightening them from the middles outwards.
* I tried the same thing, but with 15 lb weights on top of the Y-axis extrusions as I re-tightened the rails; no discernable change at all.
Has anybody seen this before, or have advice on what I could try to fix the bowing? I'm not sure if the bed is warped or if there's something wrong with the motion system, though it would be surprising to me for the motion system to be equally warped on both sides throughout the gantry corner levelling process.
