Those lines you have at 5:10 exist because of a phenomenon called ringing. It has to do with the vibration of the motors resonating with the structure. With a Prusa mini, except maybe for lowering the speed or the acceleration through the slicer, you can't do very much about it.

I bought the Mini + because of the many positive reviews and that it was supposed to be one that works out of the box, but so far I'm pretty disappointed. Assembling has cost me almost 2 hours because I couldn't line up the bolts with the sliding nuts, if 1 went in then the others didn't, and vise versa. Finally managed to get all in, then tried to mount the display, but it wouldn't grab with the 12mm bolt, and the 20mm bolt was too long, so had to get a 16mm bolt. Today finished everything, did some tests to set the nozzle height, lowered it a lot but still everything comes out like shit. lines are wobbly, the square is definitely not solid. I tried to print the nut on the USB drive 3 times now, but it's just one big mess and comes loose of the plate, the third time it went 3 layers, it didn't look that well but hoped that it at least went a bit further, but then came off the plate again. I have never had a 3D printer before, so I'm not really that familiar, no idea if it has to go even lower, it looks pretty close to the plate now. The manual is also not that clear, it shows some pictures of how the filament should look, but you can probably only see that under a microscope. On the video that Prusa shows, he only lowers it a bit and then says it is 'spot on' but he doesn't show anything, so that doesn't help either, guess I should have bought a creality after all....

The filament needs to be squished onto the bed so that it will stick. When you do Live Z adjust, dial it closer to the bed until it is so close that the line starts getting fainter. That means the bed is so close that the filament can't get out of the nozzle anymore. Then you go back up just far enough that the line is fully visible again. It might be "too close" in the opinion of some people, but for me it works perfectly. The bottom of the print comes out perfectly smooth as the bed.

If you can't get a Prusa to work due to a lack of knowledge and/or research, good luck with a Creality printer (which typically has a very poor out of the box experience requiring more time and money to get to work to the level of a Prusa). Read up and you'll do fine with the Prusa and sorry, but if you can't manage that (Prusa also has very good support, so have a chat with 'm if you need help), no Creality is going to help you.

My first printer was an Anycubic Vyper, works very well out of the box, some have had problems with the "Strain gage" used for leveling, the second printer I bought was the Prusa Mini +, big mistake, took me a very long time and many upgrades ( Bondtech extruder etc. ) get a decent print, I sympathize with your dismay
