Big 'Ol Level Tesing Square

thingiverse

This is a straightforward 160mm x 160mm x .2mm solid single layer square designed to thoroughly test the accuracy of your level. Can you make it bigger? Sure, why not? Is it overkill? Probably, but that's what makes it effective. Can it clean my magnetic build plate to an amazing shine? No, but it can easily remove old print residue and restore its original dull finish. This G-code prints a large square for setting in your level. I used to rely on a square level test that printed several concentric squares, but I encountered issues with it. The print started in the middle and only became useful after the third square when you could adjust the filament and check the adhesion. After that, you had limited time to rush through the remaining squares before having to reprint. This code prints a single square from the outside in, which works better for me. It then starts printing diagonal lines from the top left corner working its way across to the bottom right corner. As it progresses, you can see if your bed is warping or if the nozzle is digging into the lines, causing them to fail to adhere. It's a bit of a hassle, taking around an hour on standard settings and using a fair amount of plastic. However, once it runs smoothly, I know my bed is ready for extended use.
