Tells you: How much clearance your fits need.
Bambu Studio doesn't include this test: download a tolerance model (rings or pins with increasing clearances) from MakerWorld or Printables. · It works the same on any FDM printer. The menu is Bambu Studio's; Orca Slicer has a very similar one, and in other slicers you print the same test with a downloadable model. Can't see the menu?
How
- Set “X-Y hole compensation” and “X-Y contour compensation” to 0 and print the model.
- Try which pieces go in and which don't.
How to read it
The first clearance that doesn't fit marks your printer's limit: use the previous one as a reference for your designs, or compensate in the slicer.
If you paint the model in several colors, Bambu Studio doesn't apply X-Y compensation: then the clearance has to be in the design.
What you read on the piece
Draw your fits with at least this clearance. If you want them tighter, adjust the X-Y compensations 0.05 mm at a time and test again.
Where the value goes: Process › Quality › Precision, or directly in the design.
