image.jpgimage.jpgimage.jpgimage.jpgimage.jpgHi. I was wondering what causes the layers not to line up in the pictures. I thought it was z banding but my layers not lining up is random. Also, the layers that don't line up seem a bit underextruded on all sides of the 20mm calibration cube eliminating a loose x or y axis both of which i have tightened multiple times. Also, in the one picture it looks like my bottom layer was extruded inconsistently, which I thought might be connected. I initially thought underextrusion was the problem and while extruding more does help minimize the banding (see right block in pic of two black blocks), it creates overextrusion issues in other places. It seems that a high temp also helps the problem. But the temp was 235 Celsius which seems a bit high for black PLA. Any ideas what might cause this random banding? Thanks
