Looking at correcting an issue I started to have with my Ender 3v2 were the bed was not level in the middle.
Could be a warp in the bed?? I have a glass bed so not likely and ruler test confirms it is pretty straight.
Could it be my bed leveling mastery? (lol) I have done countless bed levels and thought it still might be that but then I measured the left and right Z axis and found it is a few mm to low on the none screw (right) side leading to believe that the X axis was slightly sloped.
Took apart the Z extrusions and reseated them square and tighten all screws and v-rollers. Nope not it!

Would installing a Dual Lead Screw upgrade kit help? Yes, more then likely is the answer but is there another way?
To be fair, itâs not that the glass will warp over time, itâs that it likely was never perfectly flat to begin with.
I have read on other forums something which makes sense to me but which I havenât been able to verify: Mirror glass is apparently made to a higher standard of flatness because any undulations in it will be super obvious. In contrast, you only really notice our triple-pane kitchen window is not flat when you look through it at night and the various layers reflect between themselves. Just looking at the trees outside, you wouldnât notice.
The glass bed that came with my Ender 3 was warped in the center, I replaced it and the problem went away.
It took me forever to figure out that it was the bed itself, the only way I wound up figuring it out was by strapping a dial idicator to the hotend and moved everything around to measure the distance to/from the bed. After that I hooked up Octoprint and a BL touch and used the âbed visualizerâ plug-in to verify it was infact warped in the center like the dial indicator said.
The bed on my newer CR10V3 is now giving me similar issues out of the blueâŚ
Okay itâs not the bed⌠straight with a metal square edge.
I may have figured it out though⌠sort of. I still have the slight drop on the right side away from the lead screw. But what was warping my prints was the last quarter roll of PETG. Bought another roll and problem went away. Put back the quarter roller to test theory and âBAMâ badly warped print.
Second lead screw and timing belt waits for another upgrade frenzy!
