Hello!
I'm having a weird issue (unfortunately no pics to provide at this time) involving leveling the bed. Even with my glass bed, it seems to only be really level at the center. At the extreme edges its always incredibly off, causing any printing in those areas to fail miserably (right now I'm trying to print front bezels and rear covers for 17" laptop screens being re purposed for a different project, the bezels stretch almost edge to edge on the x axis, save a couple of mm on each side).
I have tried putting on a tick layer of glue stick (one thin layer at a time) as well as blue painters tape layered up to create a cushion the hot end could then push into slightly to overcome the issue, but its never enough. It seems even if its good on the first loop around, the subsequent loops are off again.
I have tried getting a level test dial indicator and printing a small attachment for the extruder assembly for it and leveling by numbers instead of by paper. Still no luck. Can get all the level points set up at an arbitrary number, but the second pass is once again really off. Get them back to the number, and the 3rd pass is still off. That process continues, over and over. I decided to try and keep the dial in between 2 numbers, thinking maybe I was trying to be too precise, but still, every pass continues to remain crazy.
I did notice during this whole process that it seems the aluminum angles are almost like a pair of scissors; the opposite corners seem to line up. The back left and front right wing nuts are tightened way down while the back right and front left wing nuts are really loose. I checked the aluminum angles and it seems they are bent slightly. I'm not sure if this is an issue with the weight of the glass bed, as if the bed was cause I would think all angles would be bent.
I'm planning on redesigning the whole undercarriage for the bed, but would like some suggestions on how to do so. I do know that I want to move the leveling screws to the corners as opposed to the center 3rd of the bed though, I feel like that may allow a more consistent level across the entire bed. I'm also thinking of taking inspiration from the z axis and using captive nuts riding up and down a threaded rod instead of having the bed float on springs.
Anyway, does anyone have any suggestions on how to proceed?
Thank you very much!
