The first layers while printing look strange
From the first layer image it can be seen that your nozzle to bed distance is just too large:


the lines of deposited filament e.g. in the brim are not touching,
deposited filament lines are not "squished" or "flattened" to the build plate,
filament is cutting off corners as it is dragged while being hot and not stuck to the bed,
filament leaves the nozzle in "blobs"; it sort of free flows from the nozzle as the bed is too far to give resistance.


Use the plain paper technique while levelling the bed. The paper should give a slight drag/resistance when pulled/pushed. Proper levelling and a proper nozzle to bed distance for the first layer are essential for successful prints. 

There is also an option to integrally lower the print level in the slicer software, but it is advised to properly level the bed (hardware solution) instead of using software tricks to sort out the problem.
