Bed adhesion torture test

Having trouble with small-footprint objects sticking to the bed plate?

This torture test will help you check your bed levelling and find troublesome areas.

The test print fits beds of size larger than 195 x 195 mm^2.

Step 1
---
Slice and print 'bed adhesion squares.stl'. Make sure it's centered on the build plate!
Print settings:

Bed adhesion: none (no skirt/brim etc)

Layer height: 0.28 mm
Line width: 0.4

Optional, for an even more torturous test: wall count: 2, top/bottom layers: 0.

When hitting a "rough patch" on the bed plate, material that doesn't stick will accumulate and ruin a few more squares, but will likely repair itself.

I suggest you do keep an eye on this print!
