Ok thanks!
I'll try that tomorrow, when i have the time.
All the 20x20 hollow cubes look like they are not straight. The layering is fine etc, but something about them looks wrong.
Also, when looking from the front, the right hand side front corner of the build plate is seemingly higher than the left side after levelling.
So high, that the adjusting screw almost pops out any minute.
I'm still waiting for the new hot end fan to arrive, so i can go on and test that the 5V outlet on the center of the board gives power.
If it's dead, i will need to find a way to get power for the fan somewhere else.
