Help! noob in over his head with new ("used") Tenlog TL-D3-pro setup :-(

Thanks for the photos. Very useful. I've marked up a few things to look at that may give a hint as to what's the main problems might be.
First photo of the raft - seeing lots of missing lines and gaps. This suggests that you're only just lightly sitting on the bed. Go closer (at a guess about 0.05 - 0.1mm), until that first layer is "smooshing" down onto the bed.

In the second photo of the top of the print, you can see some edge lifting at least on the white parts. This is likely what the nozzle ran into and popped the print off the bed. This is because PLA needs to be cooled rapidly when doing shallow overhangs, or it tends to pull upwards into the corners. To resolve this slow the print down, and make sure the print cooling fan is running. Give the filament a chance to cool down.
