My prints were fine until a few days ago. Suddenly I started having first layer issues.
There are areas where the first layer is fine, in others it does not work (see picture).
I cleaned the build plate, also with IPA
. I tried temperature values between 200 and 220° celsius. I changed flow rate and first layer speed. I changed z-offset (difficult as there are areas where this is obviously not the issue). Running auto-leveling every time.
Nothing worked.
It almost seems the auto-leveling does not properly level, but define random areas with different z-offset (there are almost no gradients between these faulty areas, as visible in the picture it starts with a print line).
Anyone had such issues or any suggestions?
