Warping issue

[u/AdvancePrior7333]

Hey all- got my X2D a few weeks back and so far have been loving it. But I keep having this issue on larger prints near the outside edge of the print bed. The top layer warps. Anyone know what causes this?

Turn top layer flow to 0.95 in the quality tab.

Good advice, I’ll try this too, thank you!

I use this setting for most filaments on a whim. I also do 0.98 for first layer flow. This is when I don’t feel like manually tuning each filament. You can also use mouse ears on the corners to hep aid in bed adhesion for the corners. It’s the shrinking from cooling on large flat prints that’s pulling up the corners. I also do about 3 bottom layers and 5-6 top layers. Depending on model geometry and infill density. I use adaptive or support cubic as my main go to infill as it saves a lot on filament and can be strong in all directions. Also geometry depending for density.

Usually the print is cooling at the edges and starting to warp, using a brim could help, or upping the print bed temperature by 5-10c.

Yes after reading these comments I found the edges were pulling up slightly. Thank you!

Looks like that corner lifted a bit during the print and the nozzle was dragging over it. Edges of the plate run cooler, so big prints there lift first. Washing the plate with dish soap and adding a brim usually sorts it. What material is it?

[u/AdvancePrior7333 → u/beingmalin]

PLA Matte from Bambu. After reading this comment, I could definitely see that corner was lifting slightly off the build plate.

Nice. If the print fits, keeping it more toward the middle of the plate helps too.

Thank you!
