I just got a Anycubic Kobra Neo, I've been into 3d for a while but I'm new to 3d printing. I decided to go with a 2cm test cube with a built in hinge. At first I got trouble with the z axis distance and printing got wrong and loose, after some search online for Kobra specifics I got to the paper sheet help fix and everything went smoothly.

The course helped a lot particularly getting the general info on 3d printing.
