Daddy Long Legs Spiral Bed Level Test

myminifactory

It's a test that should take roughly 5 minutes, if your bed level and adhesion is good, you will have a nice spiral with a circle in the middle at the end. You can yank out the entire test from the circle in the middle and start again. It travels all over the bed allowing you to fine tune baby step Z offset parameter. If you have same line thickness all over the build plate, your bed is level or at least your probe is compensating fine enough. Designed this for 300mm x 300mm build plates. If you are using a nozzle or line width larger than 0.4mm, enable "thin wall detection" in your favourite slicer otherwise resulting slice will be empty item. I imagine it should work for smaller beds like 200mm x 200mm if you scale it down and use thin wall detection since this feature converts any perimeter narrower than your nozzle/extrusion-width into a single line.   See my Instagram for demo https://www.instagram.com/p/CMWv89TjT1G/
