Second layer, first half under extruded and another over extruded.

Hello,

My mini is a pain in an arse. I have dialled the first layer to be spot on. But the second layer have problem with under extrusion and over extrusion. I have attached pictures to show what I mean:

I have stopped extruding after that error to save some time.

My mesh points are:

I can see myself that this is no good but I have tighten the screws and it did not help at all.

Unfortunately I can not request any parts because I have bought this mini second hand and this way it is not under the warranty. Can you guys help me? Maybe it is nothing to do with bed level? I am not experienced so I don't have a clue what could be the reason for it.

Update: Third layer is ok. It looks like on the beginning of second layer the extruder slows extruding filament and then half way through increase the speed and stays on it. No clue what I could do with it.

Big update: Ok, I have to apologise. It was all to do with my Z offset and nozzle temperature. It looks like Prima Value PLA filament needs at least 230C to melt it right. I had to adjust Z offset to match the flow and it is almost perfect after that.
