NEW UPDATE: Placed Bed Bracket on the glass build plate to show that it's bent. By eye, It looks like the two folded mounting points on the right side are not quite 90-degrees. I'll contact support. Hello, My height map shows a pretty large deviation (attached). What I've checked for: - Bring nozzle to bed (glass on) and move across surface to confirm bed map. The front of the bed is ~1mm lower than the back of the bed. - Confirm all four bed screws have same number of washers, and stacked in the same order. - Confirm all screws on bed assembly are tight with no gaps. The bed feels solid, yet the heightmap shows something's off? Thanks! OLD UPDATE: I attached an Indicator to the X-Axis and measured the bed bracket at four points. The front left was the lowest point, so I set it at zero. All other points were higher relative to the front left.
Hi, Why did you take it apart? We assembly it in a jig to check it is square. What did you probe for the height map?
The height map was on glass with everything assembled. yes I understand that it came pre-assembled, like the Top-plate, to ensure it was assembled correctly and square by you all. I double-checked that I had put the bed on correctly, then removed it To rule it out as the problem. so if I understand correctly, the Bed Plate is what pulls the bracket square once assembled? Would this work, even with those folded tabs being greater than 90-degrees?
Yes, but there is still a possibility of something being slightly off, but it isn't an issue as mesh levelling will compensate. You can also do what I have done and add adjustment to the four corners to help get 90% of the off-planar error out. Additionally, if you want to get flatter than a glass surface I use a clever3d milled aluminium build surface.
Thanks for the suggestions, Greg. I ended up just shimming the bracket and got better results right away. I definitely like the idea of being able to adjust the bed height if needed. Thanks again..
How thick is that plate? I have used 1/4" aluminum tool and jig plate in the past on another printer. It was one of the best build surfaces I have ever used.
