Hi JakM,
Thank you for staying with us.
Could you share some photos with us showing your first layer?
Perhaps your relevelling is still not hitting the sweet spot, so you did make another attempt but perhaps the execution did not have the solution yet.
When I am unsure about my leveling, I usually test it by either use my finger or a tool like a screwdriver to gently wipe over the first layer and see if it moves. If it does it is still too low, if it is smooth and tightly stuck to the bed it should be good.
The strange thing, its always the same file, but in diffrenet places. the file is ok, i printed with an ultimaker2 and it was perfect.
