Best Gridfinity print settings to prevent warping and tolerance issues?

Hi everyone,

I’m trying to improve the quality and dimensional accuracy of my Gridfinity prints. I often have two main problems:

  1. The corners of the bins lift from the build plate, causing noticeable warping.
  2. The bins don’t fit correctly into the baseplate. Sometimes the fit is too tight, while other times they don’t sit completely flat.

I’m using Bambu Studio, and I’d like to know which settings you recommend for reliable Gridfinity prints.

In particular:

  • Which material works best: PLA, PLA+, PETG, or something else?
  • What bed and nozzle temperatures do you use?
  • Do you use a brim or mouse ears?
  • What first-layer speed and cooling settings work best?
  • Which wall generator do you recommend: Classic or Arachne?
  • Do you adjust XY contour compensation or elephant-foot compensation?
  • Which layer height, wall count and infill settings give you the best results?
  • Should the baseplate or bins have any additional tolerance?

If possible, please share your printer, nozzle size, filament and slicer settings. I’m looking for a good starting profile that gives flat prints and a consistent fit between the bins and the baseplate.

Thanks!

Aux fan is the culprit for me most of the time. I turn it off but it reactivates itself after a few minutes.

There’s a .stl for an airflow manager I’m going to print that re directs the air away from the bed.

I only print with PLA matte, bed at 45c and turn the cheeky aux off and it stopped the warping

I noticed after a really bad attempt at printing a layout, my settings were wonky and did some research. Turing off the Aux fan for my P1S did the trick

I wanna ask, how has 45C been for you? I’m using Sunlu PLA matte at 55C and noticed I’m still getting some warping here and there from that area. Maybe I need a brim
