u/Inner_Error_4591

Struggling to understand why my printers first layers are so bad, no matter what I do with the z offset or even changing to professional mode on the leveling doesn't help all I can think is the mesh is incorrectly applied or possibly I haven't set something up properly I've contacted support and they told me to up my temp tighten my extruder and raise my nozzle, I've done these things but I am still getiing a clear difference between areas on the build plate, yes the plate is clean, the filiment is dry and of high quality, g code re sliced and printed multiple times, gantry level, belts tight, temps are 220 on first layer 210 on others with cooling enabled, nothing is wobbly or loose, I'm so confused about what to do
