sorry for the low rez photo. I’m new to 3d printing so i’m still getting the hang of it. i’ve noticed in my prints that the bottom layers seem to barely print in certain spots of my printer.
i’m using the FLSUN 3D Metal Frame Kossel Delta and PLA
in the attached image is a thin oval with 5 mm brim and a skirt, in the top left the thickness fades off to basically nothing and im not sure why, i’ve been messing with the leveling all day but i can’t seem to get rid of it. Any suggestions or ideas would be appreciated.

Never had a delta but leveling seems to be the right thought.

what I did when I had this was to start a print and then level it while printing until all sides are equally thick.

when they are, stop the print and remove the test, then test it once more to see if its ok now
