If you are looking for displacement activities that have large amounts of slow steady methodical development of learning and new skills, with a thrilling and short adrenalised conclusion, I can highly recommend low powered model rocketry.
I’ve progressively levelled up my design, construction and painting skills, and the 10-90second flight at the end is quite a rush when you find out if your all your work passes the ultimate test from the laws of space and time, or if you’re about to instead learn something to take into the next build…
Plus, there’s usually plenty of rocketry clubs scattered around with amazing people to help on the journey…
Check your z offset, first layer squish and extrusion multiplier, then pressure advance.
That looks like too much filament or too close to the bed. Some of the edge artifacts could be pressure advance as well.
I spent a year chasing those problems out of a printer, and had hundreds of FL tests that looked just like that.
If you’re interested, Ellis 3D tuning guide is amazing. (I use a different pressure advance calibration method, but the rest has been bang on for me…)
