This is the model I used: https://www.thingiverse.com/thing:4572809
I printed these by using the official orca profile from Creality for Orca Slicer: https://wiki.creality.com/en/ender-series/ender-3-v3/quick-start-guide/how-to-use-orca-slicer-with-ender-3-v3
- Why are the squares looking so wonky? Which setting is responsible for this?
- I see some spots where the prints moved to other places, but I run bed leveling every time. Is it bed warp, or some other profile setting I need to tweak? I wiped the bed with 70% isopropyl alcohol before I printed this, btw
EDIT:
Looks like the issue was with the wobbly table. I placed it on the floor, reran the self tests, and it’s now printing a lot better!
The goal of your offset is not to be zero. Actually, in a perfectly ideal world that would be impossible because it would result in your nozzle touching and dragging along the surface on the first layer. Your actual final Z offset figure will be arbitrary based on the vagarities of your particular machine including the total overall length of the nozzle and thickness of the build plate, etc.
The actual goal is to achieve an accurate first layer which results in a thickness of 0.2mm or whatever your first layer’s height is, with minimal inaccuracy. You have to set the offset of the nozzle from the plate via Z axis adjustment such that there is a (literally) paper-thin gap between the tip of the nozzle and the plate. That doesn’t mean just setting it to zero. If setting it to zero actually worked, there would not actually be any reason to calibrate it…
